I'm interested in this subject too. If anybody knows of a CNC or 3d printed model, please post a link.

Thanks!

The same thing just happened to me. I was cutting a new spoilboard-- milling a grid of holes along the bottom, everything was going smoothly. I was watching it for awhile and then as it seemed to be...

Minor stuff I guess. I cut off the original speed controller about a half-second before I noticed the quick connects... ;-)

I did have some angst in trying to get the router reassembled. It was a...

I bought it last year to upgrade my Bosch 1617evs and it works quite well. I took photos of my conversion process if you would like to see it. I haven't had a chance to add any commentary yet, but...

Hello,

I am still a relative beginner to wood & metal machining. I have already built one CNC router a couple of years ago, and I am in the process of building my second now. So I have some...

I voted 36 inches but both of my own routers are 38 inches because of the casters. And I like the height, it works well for me. I'm 6'0".

>> If that works, then that's fine. If you keep having trouble, I'd try re-installing Mach3.

Thanks Gerry for all your assistance.

I've been cutting a sign today that I generated in CamBam, in...

I have to correct my previous post - I just discovered something. I took a screenshot of the screen while it was running. I looked at the Gcode on the left and the coords on the right-- they are...

>> Just go into motor tuning and change the steps/unit to 10x what they currently are.

When I use the interactive motor calibration function, if I set the value based on the number of actual,...

>> Just go into motor tuning and change the steps/unit to 10x what they currently are.

Yes, but then the coords are off in the display by a factor of Ten.

>> Actually, the numbers I just mentioned may be wrong, depending on how you have the microstepping set on your drives. Most Geckos are 1/10, but yours are configurable,

Hello Gerry,

Mine are...

>> I don't think you are doing the calibration quite right, when you enter the say 10mm, the next step it will ask you how far it moved, you then put this number in, (the how far it moved number, is...

>> What drives are you using? What microstepping amount? Is this a direct drive belt drive? What is the pitch diameter of the pulley? Or, what type belt, and how many teeth?

Hi Gerry,

I'm using...

>> Or just to see can you post one of the g-code files?

Here is a gcode file (Hello.zip - see attachments) that I ran last night. It was generated by CamBam and appears to be correct, I don't see...

>> I appreciate your reply but I am still not clear what "gerber" has to do with your setup. Also is your g-code outputting a g21 at the beginning of the code?

Yes, there is a g21 at the beginning...

>> Are you using a gerber post processor? I am not clear how or why gerber is involved from reading your post.

I'm using Mach3 to drive the machine, which uses gcode as instructions. I use CamBam...

>>if you go to Config > Select Native Units, is it set to mm's?

Hi Gerry,

Yes, it is set to 'MM' in the native units. Do you think it's a "bug" in the Auto-Axis calibration routine? Or am I...

>>The simplest thing to do would be to enter values in the "steps per unit" box that are a tenth of the values that are in there now.

That is what I do to cheat. But then all the coordinates show...

Howdy,

I've been building my CNC Router (an Ox variant) and I've gotten it all up and running and cut a few things, but I'm having a hard time getting it calibrated correctly. I'm using Mach3 and...

I have exactly the same problem, and I went through the same calibration technique. Originally I set it to inches and everything was working fine. But then I decided I would prefer to work in metric...
