Hello all,
I'm trying to get my HAAS TM-3P up and running, we have a CAM program that exports purely X,Y,Z coordinates, after some manipulation I'm able to get it to a workable X,Z,A system.

It's a high crossover spiral cut, but my 4th axis runs very choppy, almost as it's waiting for an axis to catch up.

Our old machines (Non-Haas) use to run the code no problem using just G1 commands.

I've tried G1 and G93 commands along with changing feedrates and I still have the same cut speed, irrelevant of F rate.

Here is a snippet, I'm running with out a cutting tool, just focusing on speeding the 4th axis up.
When I do a cut off at the end of the part it's very fast.

It takes about 30 seconds to travel 1mm on the X-axis

Thank you all.

hi....

IIRC, F40. is supposed to try and move to the next place in .025 seconds. Start with F.5 (2 seconds) and see what happens. You could also put a G1 with that G93, as you're currently in G00 during what are supposed to be feed moves.

That actually did change things a bit. The federate variable does have a physical change now. It appears if I bump it past F500. It gets very jerky again. I'm also working in mm, I do have my machine parameters set up for that as well.

Here is an updated snippet.

Disengage your 4th axis brake. It may be engaging and disengaging in between moves.

I threw an M11 command in the begging of the code, I still have the same issue.
Thanks I'll keep the M11 in there for future troubleshooting sake

The program runs a large number of lines of code at a time. Maybe you can help the optional high-speed milling.
You can also try to change the setting value 191.
191 Default Smoothness
This setting may be set to ROUGH, MEDIUM, or FINISH and uses parameters 302, 303, 314, 749, and 750-754 and
G187 to set the smoothness and a maximum corner rounding factor. The default values are used when not overrid-
den by a G187 command.
