General Mach Discussion / Tangential control +-360 degrees

« on: October 14, 2013, 06:52:03 AM »

Hello

I use tangential control but I have wires and pneumatics going to rotate axis.

I use 2.5D cam and I cant´t get A axis values.

Problem is that tangential control is turning too much.  Wires and pneumatics is rotating to axis.

Is there any possibility to program tangential control so that it is not rotating over 360 in same direction?

dspMC/IP Motion Controller / G00 problem with mach3

« on: March 11, 2013, 04:55:58 AM »

I have a problem with G00 Command in Mach3 with DSPMC. For example i give G00 Z1, The Machine goes
0,62 and on the DRO i can see 0,62 - but i wanted to have 1 mm. Nevermind what Speed. This is
always
when I use G00. If i give G00 Z5 then machine goes to 4,62 mm. It seems that machine is about 0,1
seconds without PID loop and in this time Z travels down 0,38mm.

If I drive axis from DSPMC plugin gonfig it works fine.

If I reset Z counters from plugin control, VITAL DSPMC status Z drops every time 0,38mm.

I tried to push Y axis while giving g00X0, same happens to Y axis it will lose about 0,1mm
every g00.

It does not matter if I give G00X,Y or Z.

My config is:

DSPMC  7762S

Mach3 R3.043.066

DSPMC with latest firmware from vitalsystems website and mach3 plugin from same file.

Omron U-series servos with ballscrew from IA corporation.
