Vortex A steps out of whack

Hi there - I have a MKII 30x30 with the vortex, regular long board. I have the latest version of gsender, which I upgraded a while ago. Pretty sure its 1.5.6.
Prior to this version, everything worked great with the Vortex, I just haven’t used it in a bit. Well, now that I’m back at it, I’m trying to run a job. I have VCarve Pro, I have not changed the install and have the vortex options installed for a rotary job, etc. A job is created, and the gcode looks reasonable in that its move XZ and A. When I go to run this job, however, A is stepping way more than it should. Instead of 360 steps per rotation, its like 35 (according to the A position after moving the vortex 1 turn). Surfacing (turning a piece from square to round) works fine. The job, when its doing just a round portion, revolves many times rather than 1. The result of the job is essentially a round piece of wood.

I verified I was connected via GRBL and not the HAL driver - saw that in another post here. What did I miss or need to do to fix this problem? If I manually enter G1A360 I get and unsupported message and when I ran the jobs on the machine it looked to be getting Y moves on the console - is that normal?

It’s probably something I missed with this new version of GSender. This is with open loop steppers.

@Norm258 What is your A axis travel resolution setting? With that setup, I believe that it should be 19.75308642.

Thanks for the reply. I did verify that was the value in the settings.
When using the control buttons, what value should A have after one full rotation of jog? I get 35.

@Norm258 I’ll be in the shop later today and will check. My values may not compare to yours, as I am using the SLB with a closed loop motor on my Vortex.

@Norm258 I just rotated the Vortex using the jog buttons. As I expected, a full turn of the chuck reads as 360° in the GUI readout. Notwithstanding our different setups, I’m pretty sure that yours should read the same. Either someone here or Sienci may prove me wrong, though.

Thanks. That is the result I expected as well! I will need to dig into the settings on this machine to determine what’s going on.

Since the A and Y axis share the same driver in the longboard set up, should Y be set to the same as A during rotary moves, and reset when put back?

@Norm258 No, when you move the rotary slider to ON, it will change the Y value to the A value. You will see a pop-up screen saying that. When you revert to “flat” work, it will reverse the process.

Problem solved. I had version 1.5.4 installed

It does NOT set the A value properly! Version 1.5.6 does.

@Norm258 Good to hear. I didn’t know that there was a bug in 1.5.4. I’m still running 1.4.12. I’ll close this.
