Ahh, debounce, yes of course. Mach2 config was set to 500, set Mach3 to 500, problem solved. You are very know ledgable, and I am fortunate to have this resource to draw on. Thanks for your help.

General Mach Discussion / Re: softlimits question

« on: September 24, 2008, 05:53:00 PM »

 

You need the home switches to be zero for machine coords, you then set up the slow zone distance which you find out by trial and error, Basically the slow zone is the distance it will take for your motors to decelerate from rapid speed.

Isn't that what I just described doing?
My question is, why do I keep getting a softlimit exceeded warning when the next move is away from the softlimits? If I start the same program an inch away from machine coords x0y0z0 I do not get a softlimit warning. Am I getting the warning because the axes are within the slow zone?

General Mach Discussion / softlimits question

« on: September 24, 2008, 01:36:31 PM »

I setup softlimits on my mill. I have the autozero option enabled on XYZ. X homes negative, and Y and Z home positive, so I set the - limit in x and + limit in y and z to 0, then kept the machine in machine coords, jogged to pretty damn close to the limits of the opposite end of the respective axes, noted the machine coords, and configured those softlimits appropriately. I tested by turning on soft limits, then jogging to the axes limits. I found the safe zone to be a bit limiting travel-wise, so I backed it off a bit, and the servos have no problem slowing the axes well in advance of the soft limits. When I run a program after doing a REF ALL, it immediately warns me about soft limits, even though I specify a work offset, then a G0 move that is away from the limits. Is this because the axes are still in the safe zone immediately after referencing? I think it's pretty annoying.

I tested it with Mach2, and it works fine. I read (again) through the mach3 mill setup guide, examined my configuration, checked the pinouts against my mach2 config. It's all correct. The m5 macro in mach2 looks the same as the one in mach3. The spindle comes on. mach3 inserts a dwell to allow the spindle to spin up, issue an m5 and it triggers an estop. Anyone?

I did not define an M5 macro. It is a new installation of Mach3 with pinouts and motor tuning settings (and license) extracted from Mach2 as configured by the retrofitter. I will try copying the m5.m1s file from the "macros" folder into the root.

Finally got 220V electric in my garage. Running Mach3 on a converted RF45 mill. Now I can turn the machine spindle on with M3/M4 but when I issue an M5, it shuts down the servos as well as the spindle, requiring a reset before any machine motion can be resumed. What gives?

Nevermind, I was just reading the manual. Found the tab function. Guess I better read the whole manual lest I end up looking like MORE of a fool.

I got my recently purchased retrofitted mill, which was delivered with Mach2, to run on Mach3. I cannot find a way to jog in steps within Mach3 like you could in Mach2. The continuous jog works fine via the arrow keys and page up/page down. How do I jog in increments like you could on the manual tab in Mach2 (other than MDI mode running single lines of G code)?

Yeah, I know, I know... will there be flames or explosions involved... if so, I'm in.

I have Mach3 installed and using the older license file. I have attempted as much as possible to configure the pinouts, directions, and whatnot, and I am a little hesitant to try it. It has been less than 24 hours since I got it moving under mach2. Maybe in a few hours I'll feel brave enough to try controlling it with Mach3.
