Maximum speed for the A axis?

Hi everyone,

In the config in gsender, I see that the Max speed of the rotary motor is set at 8000 deg/min. I was wondering if this was the hardware limit of the closed loop stepper or if there was any other reason for that value? I do not necessary want to machine at these speeds, but running G0 lines at higher speeds may be nice… Thanks!

@ma.dubois I can’t answer, but I believe that the setting in gSender is 8000 mm/min, not 8000 deg/min.

If it is in mm/min, it must take into account a specific mm/deg since it is the A axis?

@ma.dubois I really don’t know. To me, there is contradictory information on the Sienci site. In one place, it says, "
Simply take the cutting feed rate you’d planned on using, then multiply this out by the ā€˜feed rate multiplier’ for the closest stock diameter you’re using, this will give you the compensated feed rate you can use to achieve the desired cutting feed rate at the bit. When rotary mode is enabled within gSender, this will allow for movements on your A-axis/rotary axis that are up to 8000 mm/min, allowing reasonable feed rates when cutting small diameter stock."

However, in the tech manual for the SLB, it shows $113=8000 deg/min.

When I first replied, I was using only the information from the Vortex pages. I had not then seen the contradictory info in the SLB tech manual.

I’ve set mine to 8000, but I’ve really never timed how long a complete rotation takes. At 8000 deg/min, each complete rotation would take just over 2.5 seconds. That’s fast enough for anyting that I am doing. I really don’t have G0 moves in my projects.
