Those familiar with SkyFire know the relationship of the Mikinimech machines and the Skyfire SVM-2. I am using the SVM-2P-1A as the base machine for my new build. The changes I am making is that I will be using LinuxCNC as my control software instead of Mach 3.

I made this choice since I have previously modified two Sieg Desktop mills to add CNC control in which I used LinuxCNC. The first was a Habor Freight minimill which is closer in size to the SVM-0. The second was the Harbor Freight Small mill closer to the SVM-1. In the first case I hand scraped the ways, end finished the ball screws, and modified ball nuts so they would work as preloaded dual ball nuts. In both cases I used the Gecko 540 stepper drives. The second machine, I wimped out and just replaced the hand cranks with "homemade clamp on stepper motor assemblies." While they have served my purposes for several years, I now yearn for more capacity, rigidity, speed and accuracy. I am also tired of manually making the tool changes.

I have the SVM-2P-1A on order but to expedite the conversion to LinuxCNC I have also ordered one of the servo and Driver sets, so I can experimentally determine the best for me configuration.

In addition, since I am tired of the two handed multistep tool changes on my small mill, I have ordered the SVM-1 power draw bar. This last order will be shipped to me by Air. But I can get the draw bar, Servo, and Servo Driver with Air Shipment costs included for less than I can get the Tormach draw bar.

If any interest I will continue sharing my experiences.

My first step, is getting a computer ready to control. The computer I will be using is based on Gigabyte AMD AM1 FS1b Socket HDMI D-Sub mATX Motherboard GA-AM1M-S2H. It is housed in a Rosewill slimline microATX case. The processor is a AMD 5150 APU. quad core 1.6Ghz. It has a 64GB SSD, 4GB of ram. This computer is less than $200. I have a similar one using parallel ports to drive a stepper based homebuilt mod to a Seig X3 mill, but this one will use a Mesa 7I25 connecting to either a 7I76 or 7I77 or both daughter cards depending on how I want to configure the Driver cards. The Daughter cards will replace the USB smooth stepper in the Skyfire.

Initially I will test the computer on a home brew Seig X2 conversion using stepper motors. This will emulate having the drivers set to stepper mode. Once I receive the Servo Motor and Servo drive, I will start checking other configurations.

Of course if the new machine appeared overnight I wouldn't take the time to emulate anything.

For the spindle emulation, I have a Hitachi VFD that will drive a 3-phase 2hp Synchronous Mode with an incremental decoder for feedback. At first blush this looks somewhat similar to what is being provided as an AC servo and driver for spindle. But again this is just an emulation to get some experience with the things necessary to control this size of a mill.

I won't get very far for the next couple of weeks since We are making a road trip to visit My oldest Son in New England.

I received the tracking notice for my first shipment from SkyFire. This includes one servo, and servo driver and a power drawbar for an SVM-1 that I will use on Seig X3 that I had converted to CNC. They are due in on May 3 the day I will return from my visit to New England. I can't complain about this timing.

I have completed my trip to New England and am now waiting the arrival of parts from SkyFire and Mesa. Fedex Tracking has been updated to show expected delivery on May 5th.

In my previous post I identified the computer interface as Mesa 7I25, this should be 6I25.

Sorry I have been off line so long. I have found myself swamped with other activities. SkyFire offered to provide my machine with LinuxCNC and their schedule seemed to be quicker than I could find time to do it myself. At last report the Machine is built. Initial trials with LinuxCNC on a SVM-1 worked. The plan is to implement on SVM-2 this weekend. Just checked, they are currently testing on an Un-enclosed SVM-2 will transfer to My machine after all functions tested. The X, Y and Z axis are working, now debugging Home and limit switches. Spindle drive to follow and then moving on to the 12 Position ATC. I told them I will check back in a couple of days.

Very nice, good to hear from you. Sounds really exciting, and I am doing something very similar, I have ordered a barebones SVM2, will DIY my MesaNET and LinuxCNC solution for it.

Would luv to see photos once you have them.

Cheers Mate!

Just grabbed a screen-shot of the position of the Cargo vessel, carrying my machine - fun days, but as Murphy's Law dictates, it will be ready for collection in the next 1-2 days, but I am flying out to Finland tomorrow. Luckily I have someone in my office that will arrange clearance and delivery, so I can pick it up from my office upon return.

This is where it is at the moment:

http://img.photobucket.com/albums/v329/MrBean_PM/MOL%20EARNEST%20Position.png

Now, my machine typically comes as a complete package, with Milling cabinet, all controls, servo motors etc, ready to operate - but I have discussed my requirements with Ren, he was happy to accommodate me, and my machine will come with an 8,000RPM 3.2KW spindle, VFD, Linear Ways, as well as ballscrews, setup and ready to go, as well as couplers and mounts for the servo motors.

I will however do my own controller, as well as provide the servos, which have arrived a few weeks ago already. Also, I will order the enclosure and Automatic Tool Changer in the next 6 months - this way, I could fork out available cash to get the machine, and I can then save up a bit for the nice-to-haves....

Here are pics of my machine, just prior to shipping, it is a custom designed-for-CNC from the ground up, and this particular build, based on my requirements and specifications:

My machine is getting close to pickup time as well. It has made it through X-ray in Long beach and is being transported to Dallas. Expected release September 22. I have added so pictures of the machine made just prior to loading. This Machine was ordered to be LinuxCNC ready. complete with a 12 position ATC. Since I was too busy to work on it myself I asked them to proceed with the LinuxCNC install. Once I saw where I would now have the time, I asked them to ship as is. They still had a couple of unfinished issues with LinuxCNC as this was their first build with it. Since shipping they have provided updates removing some of the Issues. I am looking forward to the release of the machine.

Pictures will have to wait but My machine is now at the house. Two problems. The first is it will not fit through the door assembled. This means fully removing the Cabinet and disconnecting the electronics in the cabinet from the mill. Then removing the Mill from the base and moving the Mill through the door piece at a time, then reassembly. Pictures are being taken as the work progresses, but won't be posted until the work is completed.
The second problem is the mill fell over onto its back while we were moving it off the pallet. This caused some damage that will be assessed during disassembly so replacement parts can be acquired.

My current assessment is the largest step is the disassembly with the marking and recording of connections so the proper reassembly occurs.

Hi, I didn't mean I would do any emailing to prompt a reply....it was to suggest that is what I should do in your case.

I waited 2 years for the completion of the order I sent originally due to circumstances as has been noted previously on another thread.

I don't think your order has been put on the back burner indefinitely, things are happening in China, so perhaps a bit of patience is needed.

My bad!! I have been very negligent in updating my experience with my SVM2P. It arrived in late September, and ever since I have been installing and using it, but still not quite finished. I have ordered a different enclosure so I can use my gantry crane to load the table. My shop is a converted bedroom in my house so it is a restricted space in length width and height. My first problem is I had to take it apart to move it into my shop. To reassemble it I needed to customize a gantry crane to fit in the shop.
At this time it is working, but I have more to do to get the tool changer fully functional. I am also delaying the use of coolant until the new enclosure arrives. I had damaged the original enclosure when I dropped the mill on it's back while removing it from the packing pallet. Using the wrong equipment helped Murphy. It was repairable but I decided to get a modified version.

I will post again once the tool changer is fully functional.

Hi Mate,
Sorry I missed your question - yes, I have received my SMV2 as per the above specifications, and this week y custom enclosure, as well as HS spindle and 12-tool ATC will ship from Ren's premises too.

i will post pics of the Milk sitting in my garage, still on the pallet, hopefully it will be up and running in a December. I am currently working on the controller components et all.

Will post pics this weekend then :)

EXCITING Beano...........I hope you have lifting tackle to handle the mill......if it's like my SVM-0 you will have a difficult job to not damage something.

There is a difference though.....I received my mill in it's enclosure bolted down on it's sub frame to the pallet in a large packing case.....getting it out was a task.

It's OK at the send off point to handle it with a fork lift into the packing case, but at the destination the package is a vulnerable entity that has no lifting attachment points to attach ropes or slings to.

If there had been some tapped holes in the top of the column I could have screwed an eye bolt in and done a lift with my engine crane.

A much better solution would have been a 25mm hole through the sides of the column near the top so that a steel bar could be passed through for a sling to be attached.

In the end I cut 2 pieces of wood and attached them to the bottom of the sub frame so that I could get ropes onto it and do a lift with the engine crane.

All of that manoeuvre has been posted before on the original Skyfire thread before they closed it.

One things for sure....all column mills are top heavy.....lifting them with a fork lift is a dodgy exercise..
Ian.

Cheers Mate, good advice there :)

I finally got my enclosure and 12-Tool ATC on Friday. It was a mission getting the enclosure off the Budget Rental tray truck, as I do not have a forklift at home. I decided to take the top part off, undid 2 dozen bolts, but finally got the top and bottom separated, and myself and 3 neighbors manage to get it off and into the garage.

Good thing I took the top part off, as it would be easier to get the SMV-2 ontop now. Need to workout how I'm going to do that, but all in good time. Then I will split the top part in two halfs by undoing a few more bolts, and fit one side, then the other.

i will start a mini-log for it, as I still need to fit my custom servos, plus do all the e,ectrobis et al.

How's yours doing? Would luv done updates from you :)

Cheers,
Beano

Hi......You were lucky to have the labour to work on it......I worked single handed with an engine crane.........luck I didn't have to strip any parts or unbolt anything

Mine's in the garage and on the bench I bought for it.........just having fun playing with G code and simulating projects to learn the ropes etc. which is why I bought it.

Having been a manual machinists all my working.....the transition to a machine doing all the moves is a whole new ball game, one that I'm learning to come to terms with.

The weather is getting better now so the incentive to go out and mess in the garage is high.....along with the garden and a big overdue tiling project.

One thing I'm working on and that is a tool maker's vice mod that really needs to be done.

It's one of those 100mm models with the angled pull down screw type and the quick release nut at the bottom is giving me a pain by constantly dropping off the screw or the side slots.

Doing the mod is working out simple as no drastic changes or reworks have to be made and as soon as I finish it I'll post a thread on the method as others probably have the same problem with this type of vice.

HA, I need to learn the ropes too, being an electronics engineer/instrumentation tech my whole life, blah....but a good starting point I guess.

Weather is getting there, you're right, I will spent quite many of my next few available weekends in the garage getting things slowly together.

As you might recall, I got the SMV-2 with all mechanicals done and ready, but have to provide my own servos, controller, and electrics in general. That part will be easy for me, so no dramas, it is just to get it done. Luckily I have almost all of the required bits and pieces already.

Just a few pics of the stand, the first ones where it was in China still, just before being packed by Defeng - the last 2 on the truck at my place. Will start a new thread pretty soon, don't want to take yours over :lol:

After around 4 months from order to Port Melbourne, finally arrived and at my house - I rented a truck from Budget, picked it up myself, and brought it home - yeah baby.....let the fun begin...the size of it in relation to the truck, gross weight was 400kg....

Gulp....golly gee, Batman, this thing is bigger than both of us.....LOL.....when the packing case is empty you could rent it out as an apartment.....not quite a container size but getting there.

I thought your 4 Months round trip was quite good for a direct import.

When I had a look in the cabinet of my SVM-0 I am of the impression that.....you have lots or wiring and connections to make before the fat lady sings.

At least with mine the electronic parts were already in the cabin ready to go and any subsequent trouble shooting will be a headache....for me that is......fingers crossed.

I still have to install another stepper driver, one that I ordered with it, to cater for an anticipated 4th axis event....one day......but at least a position for it was already drilled and allocated next to the other three.

Then there is a VFD to find a place for the high speed spindle I also got with it.

Yeah, the SMV-2 is a rather solid and serious hobbyist machine, I suspect, pretty well loaded with linear ways and stuff like that, as you know. I think it should perform very well for the intended application, might even be a bit over-the-top, but that's ok, I really did only want to spent once on the build.

it would have been a lot wiser and cheaper to get it all in one go, especially wrt clearance/broker fees and stuff like that. But, it's done, I'm happy and finally I can start with the exercise.

There's a bit of panel-building/wiring ahead of me, but other than the need for one or two solid-state relays, I can proceed. I have most of the gear, like servos, drive-controllers, Mesa cards, switches and other bits and bobs already, including Path Pilot software and a new compatible i5 board and chip.

I think I might start a buildlog on the weekend, it might help others venturing down the same path wrt the electronics, as that side will be fairly generic in any event.

catch you soon!

Clever idea to take the casters off the engine hoist thereby reducing the clearance between the floor and the base. I'm going to have to remember that one.

How do you like the raising mechanism on those (FootMaster?) casters? I find it nearly impossible to adjust them when they are fully loaded.

MrBean_pm
10-31-2017, 08:41 PM
Cheers Michael :)

Yeah, I was doing some measurements and realised the enclosure wont be able to go over the legs of the hoist with the casters on the hoist. With them off though, I could position the mill-stand over it with room to spare.....and the fact that I could just pop off the hoist-legs via push-pins after, helped a lot. Trust me, I was thinking about 1000 ways how to do this, even thought about hiring an A-Frame hoist setup...

But sanity and logic prevailed, hehe.

Yeah, the Footmaster casters are a bit heavy to adjust if you want to remove the total load of them, but I usually just set them about half-way to provide stability. Not sure about the sensibility of this in the long-term.....but these are pretty robust units....

What's your experience on letting the machine sit on them?

MichaelHenry
11-02-2017, 07:24 PM
My 1100 lb mill has been on 4 of the GD80 casters for about 8 years or so and no problems so far. No flat spots that I've noticed. My 1600-lb lathe has been on the same sort of casters for a couple of years and they seem fine as well.

MrBean_pm
11-02-2017, 11:40 PM
Great, this one is about the weight of your lathe, so it should be fine too. Appreciate your feedback!!

MichaelHenry
11-03-2017, 07:13 PM
Don't forget that you can adjust the casters so that they are raised above the level of the feet. In that position, the caster wheels will have no load and should never develop flat spots.
