Howdy,

I have LinuxCNC 2.5 and have the steppers all cool but have one problem.

I did the Stepconfig wizard and the test axis works fine...speed/accel.

In LinuxCNC however if I do a G0 move in a g code program it doesn't G0

In MDI it does !!!! It seems like the federate is ignored as well since I tried bumping it way up... like F100.

Is this a simple fix? I'm not losing steps, everything seems fine except for this problem.

Thanks!
Nelson

Hi Nelson,

Please post the first part of you program up to and including the G0 move and maybe a few extra lines.
It will make finding your problem a little easier. Also what happens if you change the G0 to a G1 move?

[nelZ]

Here it is. Nothing fancy. The G0 lines don't go fast. In the MDI mode a G0 command sends the axis going fast, as it does in the stepconfig "test axis" also...

g0x2y0.5
g1x2y.4z1.5f50
G0x-2y-.4z-1.5
g0x0y0z0
g2x-.5y-.5r.5F200
g0x0y0z0
m30

Thanks

Hi Nelson,

I just tried this on axis 2.4.6 and 2.6.0-pre0-4472-gbc335b8 and both work fine. I don't have 2.5 installed to test it out though sorry. I can see no reason it should not work though. What is your max feed rate set to in your config files?

Sorry to jerk you around... It's working fine, my brain is slow perhaps.

I'm using 2 linear tables with different motors, screws, etc. Developing a grinding automation device.
what was happening was I moved both axes with the G0 and controllers move axes so each reaches the end at the same time. The Y axis has a pitch of 50 threads per inch so goes slow...just like my brain.

When I do the programming for the parts I'll just issue a G0 for the X then the Y to speed things up.

BTW what's your tagline mean?
