Galil / Re: Bug in Galil Found While Jogging with Keyboard Arrow Keys
« on: January 11, 2011, 04:16:07 PM »
Also, I saw this in the debug file

State.nAixs = 4

Shouldn't that read State.nAxis = 4 ?

Galil / Bug in Galil Found While Jogging with Keyboard Arrow Keys
« on: January 11, 2011, 03:54:26 PM »
When I jog the machine using the arrow keys on the keyboard, I get a runaway condition quite often. It will start jogging, and then just go crazy, zipping along down the table at breakneck speeds. I just looked at the code in the GalilDebug.txt file. I noticed that many of the commands don't have a comma between the value for the Z axis and that for the A axis. I think this is causing my problem. An excerpt from my GalilDebug.txt is attached.

My config is as follows:
4 axes: X,Y,Z,A - all servo reverse
X and A are slaved together (X is the master)

Has anyone else ever experienced this? Please advise.

Update: I am able to get the machine to home IF I push the slave axis back so that the Master (X) axis triggers its home sensor first. This may not be acceptable to my customer, so I need to work around it. Any suggestions?

Steve,

Thanks for the description of the homing routine. This has proven very helpful. I finally made it back up to the site where the machine is, and I can now get the Y axis to home properly. I simply had to home more slowly as Mach wasn't catching the signal because the home sensor triggered on then off again too quickly.


NOW, another small issue... When I am homing my X axis (to which the A axis is slaved), sometimes the A axis home triggers first, but the X keeps pushing both axes as its home signal hasn't been triggered yet. This sometimes results in a fault of the servo from pushing against its end stop. What is the best way for me to handle that? Should I write a custom home routine, or is there a setting in the galil plugin for this?

Thanks,

Josh

P.S. - would having both of my prox sensors wired to the same X home input do the trick?

P.P.S. - I do have perform axis squaring for slaves checked. How do I tell Mach the value to offset the slave when homing to adjust the gantry into squareness?

I too have been having the same problem on a retrofit I'm doing. I set the ports and pins for the home switches in Mach3. Mach3 diagnostics show the switches trigger, but Mach sends the machine to the switch, ignores the change of switch state, and keeps going.

My setup is using a Galil DMC-1842, in Servo Reverse mode. Though I am not on-site at the retrofit to test on the machine there, I am suspecting that setting to be the culprit. The reason I say that is this: I brought the control computer back to my shop to test with. I hooked it up in stepper mode to test as I don't have any analog servos at the shop. I did a clean install of mach. Installed the plugin. Configured the plugin, setup my homes and limits (just exactly as I did on-site). It worked! At the moment, I suspect that Motor Type setting in the Plugin Config.

Also, I was told that I should set my limits and homes to identical values (i.e. - X Low Limit and X home are both enabled with the same port and pin configuration). I don't know if that was actually necessary, though. The next opportunity, I will try to determine that.

Shivu, be sure to let me know how you progress on this. This issue has cost me a lot of down time, as it may have you. I hope to resolve it soon.

Thanks,

Josh G.

P.S. - Let me clarify... My vertical axis (z) actually homes correctly, but the axes that home in their respective negative directions do not.

Galil / Re: Mach3 & Galil using stepper motor and encoder feedback

It looks like galil supports that functionality, at least on some of their controllers...

Galil / Re: Problem in Motor Tuning

Just in case you ran into the same problem as I did... Go to Config > Ports & Pins > Motor Outputs. Make sure the axes you want to run are enabled with the check mark. Last week I was unable to use the Motor Tuning menu in mach and the graph was not working right either... It was because I had not enabled the axes in the Motor Outputs tab.

Galil / Re: Homing Problem
« on: December 29, 2010, 10:10:41 PM »
Shivu,

I don't have a solution to your problem. I am having the same problem! I am curious: what are your settings in the galil plugin? Specifically, under Axis Setup / Motor Type? (Servo motor, servo reverse?)

Also, what are your settings under Homing?

I look forward to your reply. Maybe we can help each other figure this out.

Josh

Galil / Problem with Homing - Mach and Galil
« on: December 24, 2010, 09:14:33 AM »
I am having difficulty getting the homing to work properly on my machine. All the home switches show up in the diagnostics screen and respond as they should. My Z axis homes fine. But when I try to home my Y axis (home neg is checked in homing and limits screen), the head comes to its homing sensor, the input light triggers in the diagnostics screen (it actually slows down briefly) then it keeps on going the same direction and pushes against the stop and faults the servo instead of backing off the sensor and setting that position as zero. Any ideas?

My e-stop on my machine is wired into the Abort signal on the ICM-2900. What is the Port number and Bit number for that to enter on the Estop setting in the Ports and Pins dialog?
