Hi TOTALLYRC,

I've tried the settings you posted. With scale of 100 the machine shakes real hard and trip follow error an also get error in the servo driver ( Over Current). Then I've tried with scale of 1000 with the same pid setting and get better motion.

ok thanks. I will try your settings and let you know what happens .

Hi Mike,

If I set D in X-axis 25 times higher than P I instantly met follow error and must set max error to 5000 to execute motion without error and overshoots the final position for 30 to 40 counts.

Hello,

I have done settings in axisworks also without s-curve with almost the same graph and still get bad resaults in mach3 when running g code. If I set accelerations 5 times lower the results are better but my machine is capable higher accelerations than I have set now. Now I'm running my servo drives in voltage mode but I will try running them in velocity mode to see if it would be better.

Hello alfaalfa,

thanks for reply. Yes I have CV turned on and I have played with CV parameters but couldn' get good results. Here are pictures of  my graph in axisworks for x and y axis

Hello,
 
I have not been doing anything on my machine for a few months. Now I'm back in my workshop and I have some questions. I think my tuning graph in axisworks looks ok, but when I try to run g-code in mach3 the accelerations in the sharp corners are very rough. It sounds very rough in change direction in high speeds. Is that because mach3 outputs trpezoidal motion? In mach3 settings I have to set accelarations and speeds ~4 times slower to achive more smooth motion. I'v tried to use tempest planner in mach3 which puts out s-curve motion and it was smoother, but tempest planner is not fully supported. Is there any way to achieve smoother motion in higher speeds?
 
Best regards,
Peter

VB and the development of wizards / Macro M6 safety

« on: June 15, 2010, 04:34:01 PM »

Hello, I need help with my M6start macro. My spindle has these outputs:

spindle stopped - input14 is active
spindle running - input14 not active
tool in spindle - input13 is active
spindle chuck is open - input12 is active

Now I would like to put in some safety. I would like not to do a toolchange if the spindle is running, and also if the tool is stuck in spindle. I noticed yesterday that the tool was stuck in spindle after long cutting. That could be disaster if machine was doing toolchange.
So please can someone help me what code do I need to put in my M6 macro and where in code to prevent this to happen. Attached is the M6 macro. Thanks.

Hello, sorry for late answer. I was away for few days. The new firmware is working perfectly and I can change the direction of rotation for slave motor in axisworks tuning with trajectory generator and with PC host software to change direction for slave axis to work with mach3. Now all I need to do is fine tune all axes. Can someone please post a picture how perfect graph should look like. Thanks.

hi Peter,

I just sent you email with new AxisWorks software and firmware.

copy the exe files to c:\program files\dspmc folder.  also read the readme.txt file.
 
update the firmware with new version before running mach3 or axisworks.
 
you load the xml file in AxisWorks to tell it which axis is master and which is slave.  you select master axis when connecting to dspmc.   the new axisWorks will ARM pid for both master and slave.  when you download pid settings, it will download same pid values to both master and slave axis.  and when you save pid settings, they will be saved for both master and slave axis.

Let me know how it works.

thanks
Rufi

Hello,

I recieved new firmware for slave axis tuning. It's working. I can download pid setting for both axes and tune with both axes exept there is a problem with direction of rotation for slave axis motor. I'm drivig my machine with rack and pinion and I need slave motor to rotate in other direction. I've recieved new firmware from Rufi to solve this problem. I will try it out tomorrow and report how it works. Thanks.

Hello Rufi,

were you able to write new firmware so I can tune slave axis in axisworks?
