ittai, I can't give you any advice myself. Sounds like you have tried all the combinations though. I never bothered to "fix" my limit switch problem because the machine works ok the way it is. I have seperate home switches before the limit switches, so I never hit limits unless I am doing something wrong and even though I cannot drive off the limit the most inportant thing to me that the limit does stop the machine. I just have to manualy move the axis off the switch.

I would suggest setting your limits up as normaly closed. Others are using N.C. switches and have no problems.

I don't know about either of those drives you mentioned, but I do know Automation Direct drives get good review. If your interested in the AD drives, I could save you a few bucks. I have one brand new 1kw drive and motor with cables (about $1400 on the AD site) I'll sell you for a lot less then that. I was going to use it on my gantry router build but decided to go a different route. Let me know if your interested. Good luck with your conversion.

Played with it for a few minutes tonight. Noticed that if I turn off (disable) the limits in ports and pins the Galil hardware will stop the axis motion in the direction of the switch and will allow me to jog away from the switch. Suppose I could let the Galil hardware handle the limits and homes and just have it send a signal to Mach if a limit is tripped??

Anyway, I'll keep picking at it. I want to try making a new profile from scratch, maybe there's some odd setting that got changed.

Hello, I asked this in the general forum and they thought I should ask here too as it may be a Galil problem.

Alright, I recently wired up all my homes and limits. During testing I intentionally ran into a limit, Mach went to EStop and the servo drives went in to standby. Great so far. Then I hit the "Override Limits" button and reset Mach. The servos enabled BUT Mach never came out of EStop. The servos are active, Mach is in EStop mode and there is no way to move the axis or disable the servos without powering down and manually moving the axis off the switch.

So, that's the problem I have. Any help would be appreciated.

Here's a quick video of what I explained above.

Ok, I played around with this for a few hours today and nothing seems to change this. It seems like the "Limits Override" button on the settings page has no functionality. Mach will not clear the EStop with the limit signal hi. Should I try re-installing Mach?

I uploaded a video showing the behavior of the limit switch being triggered. Maybe that helps.


Also included the Galil debug file and the xml and the last errors file
6  Mach Discussion / General Mach Discussion / Limit and home coordinates questions on: May 07, 2011, 11:21:21 PM
A few questions maybe someone can help me with??

1) When I trigger a limit switch (intentionally-for testing purposes), I cannot get Mach to let me move off the switch. I tried checking the "Auto limits override" and the "Manual override" but neither seem to work. Mach will not let me reset after a limit trips until the limit is manually deactivated.

2) I trip a limit switch and Mach goes into reset as expected. At this point if I hit the reset button my servos are enabled but Mach still is in a RESET mode and will not come out of reset.

3) How do I get Mach to automatically set my coordinates after a REF ALL? I have my Y axis home switch in the far positive position and would like Mach to set coordinates appropriately for the Y axis (it should be at machine coordinates +34.00 not 0.00)

I"m running Mach 3.043.022 and the Galil Plugin with a DMC1856

Aha, index input for each axis, that's what I missed! It makes sense now.

Thanks Kenny.

I found this in the manual for the drive. The drive has a "0" position marker pulse it outputs, but the pulse comes out on a separate terminal then the main channel a/b. As far as I can tell, the signal is not included on channel a/b. Is the Galil looking for this index pulse on the A/B channel?

BTW,  I am using SFD feedback as mentioned below.

From the Danaher S200 Drive Manual  ""The CH Z Output is only available when using SFD
Feedback. These two terminals function as a differential,
TTL marker pulse. The output pulse occurs once per
motor shaft revolution, starting at feedback device
position = 0. Its width is one line width or two quadrature
encoder widths. The CH Z uses the same differential
driver as described for CH A and CH B.""

Could this "Z Channel" be connected into the Galil? How?

I have read where you guys home to a index pulse. I am trying to understand this, I searched the forum but can't find any specific info.

Specifically where does the pulse come from and where is it connected to on the Galil ICM breakout?  Is it sent from the drives though the a/b encoder output? On my drives I know I saw a reference to a separate output for index +z/-z I think it's referred to. Do I use these? Where on the Galil ICM would I connect these? Any info would be helpful, thanks.

Sorry I don't have any input on the spindle, but I do have to ask....what's the story with the Firebird?

The Firebird is a 1969 convertible, originally had a 350HO however the motor was missing when I purchased it. It now has a worked 455 with KRE heads, roller cam, etc. It's mostly done but still needs a little work on the interior. I've owned it for about 17 yrs. Done 2 restorations on it! You may see it at a car show this summer if you live near me.
