Yes you do. Ihave the 3 x nema34 with 3 x 60v power supply units. There is no other way of powering the breakout board which comes with it (DB25a) unlss you use an additional power supply. This...

Hey Guys,

I alreayd have a copy of solidworks and I installed HSMXpress which is awesome, I found it was really easy to learn and use, But I am starting to hit the point where I need to do some...

Hey Mate, I actually had luck with using the EMC post processor in HSMXpress and uploading it to ChilliPeppr when I was using my arduino setup.

do you have a paid copy of HSMworks? if not,...

Well I worked it out Thanks to a little help from the linuxCNC forums. Trying to calculate it came up with 200 steps (360 degrees divide by 1.8 degrees for the stepper motor). if i tried that with...

Hi There,

I'm having problems trying to get the right machine settings with using LinuxCNC, 16mm ballscrews and Nema34 direct coupled stepper motors with LinuxCNC. I have an accuracy of 0.5mm but...

thanks heaps for the reply, I think your 100% right, .. when I setup my tooling, I set most of the lengths of the tool to be 25 to 50mm.. them homing the z axis from the tool touching the...

Hey Guys,

So I have successfully engraved a piece of wood with LinuxCNC (the default gcode that comes up in linuxCNC) however after designing a part, post processing with EMC in hsmxpress and...

@engele Thanks for pointing that out. I didn't think it would be that easy.. I'll make a copy of everything and set it up over the weekend and put a zip file up here with the contents(No...

Im using the drivers that came with it as a kit. ( UK Ship 3AXIS Nema 34 Stepper Motor 1232oz IN 5 6A CNC Plasma MILL | eBay )
The drivers are DM860A which seem to work fine.

My bad.. Should be public now (possibly why i haven't received view for it yet lol..)

It was actually fairly easy.. What I did was I watched NYC CNC do a video on Chillipeppr ( https://www.youtube.com/watch?v=gzLYNSQEPDk ) and using the stepper motor drivers I got from Long-motor on...

hey if your setting up a cnc router with ballscrews and stuff. to get you going, I would use GRBL with chillipeppr CNC controller. Providing you are comfortable with wiring, its by far the easiest...

Thanks I actually didnt end up using the tinyG, I just used an arduino uno with the grbl software on it and wired it up (at a cost of about $13AUD for the arduino) I did find that using it with...

Anyway I got my CNC Nema34 Motors today. Im wrapped.. I got a breakout board with it and I will probably use it.. But At the moment for testing and a big maybe, I have it hooked up to an Arduino...

I got a 3 axis nema setup from longs-motor.. I just received the wiring diagram as well.. It makes sense.. It doesnt seem too complicated, It just refers to needing an additional 5vdc/2A power...

Hey, nice work.. Old thread I know but... How did you order the right sized ballscrews? This was the only thing that put me off buying everything DIY.. So I got a cncconversionkit instead.. At...

haha so is this the 'hand crafted' stuff that is made by 'villagers' that is on offer in the markets? lol...

Thanks mate. However the standard with mach4 is they are moving away from parallel ports and moving towards USB/Eth. Generally I have found parallel/rs232 serial to usb converters cause more issues...

the gecko drive and homann referred to only offer parallel port. Why is it that they still use the legacy ports instead of USB or ethernet?

Im wondering if I can get arduino grbl working with...

hey mate, ebay 100%
as a matter of fact, I almost bought this CNC Router Engraver Engraving Machine Milling Ballscrew Desktop Brand NEW | eBay

Cheapest way to get it. Then I went to alibaba, ...

Hi Mate,

I hope you didnt buy from redfox. I spoke to him about coming to have a look at one, made the 30min trip down to see him just after lunch and he wasnt there. So then I spoke to the girl...

Hey Mate,

I have also been doing my research on these little buggers as well. I have found there are 2 main stepper motor manufacturers on ebay longsmotor and wantaimotor.. For my application...

Hey Guys,

Old thread I know but certainly worth reigniting. I had the same issue trying to source metal. I went to the local steel suppliers and got a heap of AS3679-300 grade steel which was...

Hi All,

I am looking at converting my bf20l to cnc. But I'm curious why the optimum ballscrew kit is a bolt on kit vs any other ballscrew kit which requires milling the Y table? is it the fact...

Hey All,

Hows things? So I have had my opti bf20l for a couple of weeks now. Slowly learning the capabilities of it and seems like a good machine.

Newbie Lessons learnt so far are...

Hi All, Troy from Melbourne, Australia here.. I have been a long time reader.. After taking delivery of my opti BF20L 2 weeks ago and playing around with it. I thought I would sign up and...
