Monarch Vmc-150 Retrofit

[wild01]

Hey I'm about to retrofit a Monarch vmc150 4 axis mill with 30" x 70" travel (I think) I am in southern Colorado. Before I convince my boss to make the initial investment I would like to know how much smoke the salesman blew in the general direction of my posterior when I called.

First off understand that I am needing to get into this machine as quickly and as cheaply as possible. It was purchased with an eye towards production and it has cost far to much already. I do plan on upgrading a few things at a later date, but for now it needs to pay its way a little.

I was quoted cnclite for temporary control, with an eye towards upgrading later.
(side note I am a full time student and I noticed in another thread it may be possible to get my hands on a student version of pro for around $500, anyone with details please give.)

1 cs21720 7 axis ethernet dsp based controller card

1 usb jogstick

the sales guy told me I should be able to get most of the install done myself with phone and video help from camsoft and should only need someone onsite a day or two. (please note he of course did include all neccesary CYA statements and never guaranteed any of this)

what I need to know is how realistic is this, is there a better route, and what do I need to know before shelling out my bosses well horded money, and is there any installer out there who would like an all expense paid trip to the beautiful san luis valley for less than $620.00 per day.

From what some guys have told me about Monarchs, there's quite a bit of stuff to try to interface on one of those babies, what with the floating Z axis for tapping, toolchanger, etc.

How to advise you? Hmmm, there's no way in hell that that machine is going to be ready to go in 3 days, if you attempt to do it yourself. If you can find a competent retrofitter who actually has experience doing one of these types of machines (a Monarch), you'd be well advised to get the guy down there for $620 per day. His knowledge would be cheap at that price. You can make more money hand-hacking 6" stainless round barstock than you will retrofitting it yourself

I highly doubt that cnc lite is adequate. You can almost bet that some of the nitty gritty details will force you to get cnc professional. Thats 5 large up front.

Edit: I'm not saying the Camsoft system is bad. But, there is a lot of road to travel for the beginning retrofitter. Chances are a "pro" would come along with a pretty good cbk file that would represent hundreds of hours of time spent figuring out good logic.

Wil,

Let's try this again. It's important that you understand this properly and consider everything that was said, including your budget and the CYA statements. In the manner you presented it here in the forum, we would also say this is not realistic. The CYA statements we made were as follows:

CNC Lite to handle the hole drilling job only that you have currently for it.
Conserveritally speaking 6-8 weeks
You would require a electrical/mechanical installer
(cost & time of their service unknown until you're ready for their visit)

There is a student version sold to schools for $495. It is CNC Professional, but there is no hardware and isn't capable of moving a real machine.

You don't have the budget to do any more right now. Perhaps later as was talked about. You will have to upgrade to Plus or Pro bring this machine with in standards. As we mentioned CNC Lite would only be temporary. For the hole drilling project it would be okay. Because of the I/O requirements of the tool changer you may have to only use one drill and not use the ATC until you or the retrofitter can determine the actual I/O need on how this tool changer works. The CS-2172 has only 53 I/O.

To respond to your post huflung
I apreciate the imput. If a profesional installer can do this in 2 or 3 days I don't think my boss would have a problem paying $620 a day although he did kinda balk at 200 a day perdiem, as we only charge 100 for our onsite, and the cost of lodging is pretty low around here.

What I am trying to determine is if this is really something I can do with only 2 or three days help. (and not take 6-8 weeks of my own time on the clock 2-3 would be acceptable.)


also, why isn't lite adequate. camsoft did mention that it was kinda lite, but the features that they used to point out it's weaknesses were features not included in the original control. backlash compensation ect.

what I need to know is, is lite capable of running the tool holder, will I have to start from scratch if I upgrade to pro ect.

Wild,
If the Camsoft people can connect you with a few professional retrofitters to talk to, they are the ones who can give you a good estimate of the costs. Typically, they do not want to have you rip out all the old control wiring until such time as they have gone through it, and understand it. If you have electrical schematics for the machine, it will help them immensely. They need to understand all the I/O for that machine, because basically the same I/O will need to be functional within your camsoft interface.

I would say you need CNC professional because of special needs of that machine. With CNC lite, you do not have full control of the logic sequence used within the gcode logic itself because you cannot write your own. While most Gcodes are quite straightforward, some may require extra logic to work correctly with that machine. CNC lite uses basic gcode command logic, and I don't recall if it executed first or last after any additional commands that you might write yourself.

CNC Professional also has more commands for you to use. Having said that, you can certainly begin with the Lite, and go as far as you can with it. Camsoft will tell you when you cannot go any farther within that system and need to upgrade. Expect to upgrade, is all I am warning you about.

Do you have this machine on your premises? What information can you gather about the drives for the servos? Is the machine in operational condition right now, or does it have control faults?

As someone who does retrofits for a living, there is no way I would talk about doing a retrofit in 3 days, even if I had all the documentation from doing an exact same machine, actually I have found there is no such thing as an exact same 20yr old machine. There is either some changes that no one has documented or wiring that need replacing or upgrading of contactors etc, not to mention servo tuning, there are always suprises.
There is pre-retrofit leg-work in comparing documentation etc. Once the machine is running there is often further de-bugging and tweaking to do.
If you add to that the learning process for someone doing it for the first time, you can triple the time taken, easy.
Al.

Thank you for your replies they have been very helpful.

I would agree with the last entry that retrofitting this machine or any machine is not a fast process. I have done quite a few retrofits with different kinds of controls including Camsoft. It usually doesn't take long to get things like I/O working and servo motion but to debug every aspect of the system is what takes time. When OEM's build machines they work for a long time debugging the controls and still sometimes have problems that have to be solved in the field (trust me I know). I am not trying to be negative but it will take longer than a few days.

[Ben Olson]

for retrofitting a VMC, IMO, cnc plus should be considered the minimum requirement

2 or 3 days is an absolute impossibility for a retrofit of that size... even the folks at Camsoft couldn't do it

spend the money or spend the time... they cost the same in the end

[wild01]

thank you all. I was not trying to indicate that camsoft had said, or insinuated it would only take a few days to retrofit the machine. Just that I should only need 2 or 3 days HELP to set up the machine. i.e. they insinuated that I should be able to get the machine to a point where it would only take 2 or 3 days for a professional to finish the setup and that everything else should be able to be acomplished by myself or with the help of a competent local electrician.

question, is there anyone out there who would be willing to give a guaranteed install qoute on this machine. Yes as camsoft indicated, money is very much an issue right now, however I would rather spend a little more and have a machine that works, than one that doesn't. also, as I indicated in my request to camsoft time is also an issue.

I did not in any way start this thread to badmouth camsoft, from what I've seen and read they have a very good control package, and I would very much like to persue this avenue. However I have done enough sales in my life to know when it comes to technical advice before the sale, you will always get a "best case" scenario.

yes the machine is onsite, it has gettys drives, I have all the factory electrical schematics, no the machine is not operational, it lost it's executive, and the tape reader is not working properly, so reload is not an option at the moment.

FWIW, I originally had the exact same plan you propose. I spent a month pulling and testing wiring and I/O. Maybe 4 hours a day actual work and 4 hours a day learning. All this getting ready for a pro to help with start-up.

The professional retrofitter I had hired wasn't able to make it out 'cause he was on another job. So, I just kept pluggin' away. Never did get him out here.

I must say I had previous expereince doing this sort of thing with a simple CNC control. And computers, wiring, electrical logic, machine problem solving, etc. were familar to me.

Camsoft has hugely more capablity than any other control I've seen. (Mach 2 is a pea shooter,Ahha is a rifle, Centroid is a cannon, Camsoft is a nuclear weapon) This, of course, makes it more complex with a steep learning curve.

The key was to break it down into simple bite size goals. Estop circuit today, limit switches tomorrow, more inputs the next day, and so on and so on.

All told, I spent 3 months on this machine. I could do it again in less than 1 month. 3 days with a pro at initial startup would have saved me more than a month.
