General Mach Discussion / X axis moving as Z axis
« on: November 28, 2018, 01:28:10 AM »
Ok so super weird thing going on and I've spent several hours trying to figure it out.

I'm using a HF mini lathe that I converted into a cnc. I've been playing on it and playing with it cutting acrylic. Well I've been running small sets G-code, so I never really paid too much attention. 

I exported a part from fusion 360 to my computer with mach. I load the G-code and start the cycle. On the regen window everything looks like it should tool path wise. But the Z axis is suppose to move first, and I noticed the X axis was moving( when the Z axis was moving in the regen window). However when I jog, the axes are correct.

My initial thought was it had to do with the post processor. But if the regen tool path is correct, and runs correctly in that window, then it shouldn't be the post processor.

I tried messing with the homing and pins setting but it's not a matter or it moving in a positive or negative direction. The axis are just moving when it's not suppose to.

In fusion 360 I realized that the turning axis is the Z axis. When on the lathe it's technically the X axis turning. So I thought that might be the issue, if it was, then technically I would need to use X and Y axis. There is no Y axis code generated in PP and no option to replace the Z axis with a Y axis in mach3 turn. So I assume that is not the current issue.

Any idea? Not having a search really sucks.

General Mach Discussion / Need some help trouble shooting
« on: November 27, 2018, 06:04:54 PM »
Hey guys!

So long story short, I'm a newbie to cnc. I'm using a HF lathe conversion to try and turn some acrylic blanks.

I'm using fusion for cad/cam then exporting G-code to run on my laptop with mach 3(windows vista). I've been trying to find the sweet spot for speed and depth when it comes to acrylic so I have been making several different programs and running them on scrap. After running a few programs today, out of no where the cnc just stops.

I started looking in the G-code box and back up a few lines and start cycle from that point. It gets to the part of the G-code and stops again. So I figure maybe something happened to the G-code file. I load several more G-code files and it does the same thing on every one of them.

On N24 the cnc just stops. Mach 3 keeps going like the g-code is executing. If I stop the G-code I can jog, no issue.

I restarted my computer, sa ???me things happen. I reinstall mach 3, same thing happens. Any idea where I should try trouble shooting? Keep in mind all the G-code files I tried running were ones that ran successfully this morning and last night.
