Re: Designing a new router called Brevis-HD
Yes the SKR and Octopus are complete control boards. Sorry if I was mileading. It's normal for Marlin to be a stand alone appliance controlled by a lcd screen with a rotary knob and a micro SD card port. Klipper offloads most processing to another computer, normally a Pi running Mainsail, Fluid, or Octoprint and you access the software via a web console. There is a windows app for PC called Klipperiod but I haven't had any experience with it.
Quality control with BST. Interesting. I just recieved a 1360mm 1616 ballscrew from bst. The end was just a bit oversized and I could not with any reasonable force get the support bearing on. Easy enough to resolve but should have been QC checked and rejected before being shipped. Hard to complain given the price point.
Re: Designing a new router called Brevis-HD
Hi Jack - The ballscrew ends I have spoken to BST about before. Seems one in 4 ends is a smidge too big. Easy to put in lathe and wipe but would be good to have them right. Especially if ordered on behave of client and sent somewhere. But the price is right as they say. Peter
Re: Designing a new router called Brevis-HD
Hi All - The new spacers have arrived so I can get back to the ballscrew assembly. These comments should have been in the Frankenrouter thread.. onward and upward. Peter
Re: Designing a new router called Brevis-HD
Hi All - I am rebuilding a little cnc that uses 10mm belts. I don't like U drives as they bend the belt in two directions so I prefer a motor with a return pulley end. I have been think of putting a motor on each end. But one side of my brain says that won't be good as the motors would have to be in perfect sync to provide more torque. Otherwise the torque/tension from one motor will "stop" at the other motor. Has anyone done this and found it to provide more torque? The aim is to make the belt stiffer by halving its length more then the gin in torque. Peter
Hello, can you please share the settings that you used to JR100Originally Posted by peteeng
Thank you
Re: Designing a new router called Brevis-HD
Hi Cronic - I use the as delivered factory settings. But here is the manual. Peter
There's the manual that nobody can find >_< thank you so much peter
Re: Designing a new router called Brevis-HD
Hi Cronic - Ask nicely and most things are available. And the English is not too bad. Peter
Re: Designing a new router called Brevis-HD
Hi All - Not much news about Scoot except I'm starting to get dust control under control & an air/mister blast nozzle. On another project I have had to size some ballscrews for a 600Tonne press, works out they will be 80mm dia or 120mm dia depending on a couple of things. They will replace a hydraulic ram. They will be 1m long, 4 needed for the machine and I expect they will cost quite a lot!! Peter
Re: Designing a new router called Brevis-HD
Hi Jack - I have just ordered more ballscrews from BST. I spoke to them about the bearing land size and they have agreed to machine them to a g6 fit vs their std fit. This is a smidge under their std so should be a light slide fit. They arrive in 2 weeks so will know more then. So if ordering screws spec the g6 and they should be fine. Peter
Re: Designing a new router called Brevis-HD
Hi OCD - So if your only doing panel work your accuracy requirement is not high. Print NC bolts square rail to standard cold formed RHS. This is potentially a pain point. There are many threads here where Makers do this and the cars immediately jam. So pick your RHS carefully. Plus the Print NC mounts the rails on opposing sides so you cannot level them in that direction. Even the paint thickness can be an issue. I'd look at heavy aluminium extrusions vs the steel, I'd expect them to be straighter then the steel sections. Make your Z as low as possible if you only doing sheet metal work. Once Z gets up you start to need lots of rigidity....Keep chasing the Grail like we all do
By the way rigidity/stiffness is not related to mass. My current best choice material is beryllium, less dense then aluminium at 1850kg/m3 but stiffer then steel at 287GPa.... Used lots on spacecraft...If your only doing light panel work consider a vertical or near vertical bed machine, saves a huge amount of floor space. PeterHello everyone.
In 2022 I will produce a similar product for a customer, supposedly processing drone housings, and I will upload my work to the website. Happy to share with everyone.
If you need mineral castings.You can contact me, my email:ma-machine@foxmail.com
I'm from China,My company has produced a lot of products, small can reach 100KG, large can do 46 tons.
My English is very average and I don't know how to upload photos. Very reason to share my product with you.

Re: Designing a new router called Brevis-HD
Hi All - ballscrews and bearings from BST have arrived and the g6 tolerance is good. A light slid fit on all lands. Very happy. I bought some DLC coated bits today to do some more aluminium work. Will see how they go. Peter
Re: Designing a new router called Brevis-HD
Hi All - Scoots job today was to make a new bit holder. My rough one is full and its time to update it... Peter
Re: Designing a new router called Brevis-HD
I haven't updated for a long time, and I made two styles of similar machines,
one is the link I sent (This displacement is only 1000mm, and the door width is only 550mm.The weight is only 600 kg),
and the other is the picture I sent(This one is very large, with a door width of 3000mm.The weight is 29 tons).
Re: Designing a new router called Brevis-HD
Hi All - Scoots job today was to make a new foot plate for my circular saw. A couple of weeks ago I tripped on the cable and the saw hit the concrete pretty hard bending the magnesium alloy foot plate. I suppose its a saw foot... I pondered panel beating it but decided a thicker foot would be better, Occasionally the thin foot slips under my fence when I'm cutting up plywood. So measured up the metal foot and made a ply foot. Worked a treat.... Officially this Scoot is Scoot No5. Its probably time to make a new one that includes all the updates which would make it Scoot No7. These include a higher Z axis, a metal machine base vs the MDF one and a better spindle that Scoot No6 had... I'm about to build a big machine for full sheets I suppose then it will be time to retire the workshop Scoot. Then Scoot will be at full development, I don't see anywhere to go with Scoot after that... Maybe an ATC.... Hmmmm. Peter
Re: Designing a new router called Brevis-HD
Evening All & Sundry - Scoots been busy making Double Bassoon pipes and parts for the new routers bench. The pipes are interesting because they are long thin and tapered which means what toolpath strategy do I use? Parallel gets weird at the steep edges and 90-deg to the length would double the path time. A few simulations and parallel it was using a fine stepover. The bench is for Lanky, a full sheet router in development. Will have helical rack and pinion drives with laminated aluminum/plywood parts. I hope the saddle will be cast Sika3350 grout. Its footprint will be 3mx1500mm about. The gantry is going to go longwise so its 2.8m long... This will allow easy front loading of full 8x4ft sheets.. I'll set up a thread as I get into it... Peter
Re: Designing a new router called Brevis-HD
Hi All - Todays work was more on the Bench No2 for Lanky. Lanky is to supercede Scoot. I completed the bottom frame, now onto the top frame. I did this with too many 45deg angles. Too hard to build! But come together well. Peter
Re: Designing a new router called Brevis-HD
Evening All - I have started a new thread for Lanky. Enjoy. Peter

Re: Designing a new router called Brevis-HD
Good Afternoon all you lot - For a long time I have been looking for a one control box solution for my routers. I have tried two different Chinese controllers with mixed success and I wanted to try the Californian Buildbotics device but they were out of stock when I wanted one. I came across the Nighthawk made by an Australian company that seems to tick all the boxes. The company CNC3D is relentlessly developing the machine controller software and hardware and has taken some of my requests on board such as input shaping. So I'm happy to give them a try. So I have rewired my small router/laser with the device. A couple of days ago it ran a program for the first time and I'm pleased with the support and ease it has gone together so far. The Commander software can talk to the Nighthawk via WIFI, SD card or USB cable plus it will run from my phone when I get a bit more confident with it. The other aspect of the controller is that its a full 6 axis jobber. So I'm designing a 5 axis router as well. Plus Lanky the 8x4 router will use the Nighthawk. Its really pleasant not having to deal with all those components and wires for a week plus!! Peter
