RE: [CAD_CAM_EDM_DRO] acceleration profille

You have the max steps per seconds is way too high. Start at 1500 not
15000 then adjust upward till it starts losing steps then back off about
10%. Also your acceleration is way too high. Start at 1000 sps. Also the
start velocity is high start at 500 and increase.

Subject: [CAD_CAM_EDM_DRO] acceleration profille

Hi,

Having some problem with the z-axis in the cnc'ed sherline with
Sherline stepper 1/2 winding, Camtronics 2A driver, desknc black box,
with the parameters set up as follows


Acceleration=5000
maxsps=15000
start_vel=5000
steps/mm=400

The z-axis seem to be loosing steps very badly. The z-axis seem to
jerk, and hardly move. I set the accel. to 500 and start vel. to 500
and problem persist. I think it may be the parameters may not be
suitable for this configuration.

Can someone suggest a suitable parameter for this set-up or let us
know about the parameters which is working with your system.

Thanks in advance
