Re: [Emc-users] Just in case anyone is interested in my tool changer...

Very very cool. Your tool sensor is on the end of a pneumatic ram? It moves down slightly when touched. Is that when it makes contact? It doesn't look like the ram moves down. Just the sensor. How do you calibrate the tool sensor? Thanks John Dammeyer > -Original Message- > From

Re: [Emc-users] Axis limit warning

Hi Gene, Which for you are metric. I do a lot of metric, but the machine was originally setup in inches. No problem. Just change the G21 to G20 in toolset.ngc Neat, but my screws limit me to on table positions, so I usually just superglue a piece of dbl-sided pcb to some handy place near the

Hi Gene, I don't have a joint.N.pos-fb,but I do have a joint.N.motor-pos-fb. That's 'cos I can't type... :-[ But, in order for it to be consistent, I have to "rm hm2-stepper.var" AFAIK that file stores persistent parameters. I have no idea why you should need to delete it. I'll have t

Re: [Emc-users] Axis limit warning

Hi Gene, But homing does not apply a TLO, which can vary by 7 or 8 inches according to whats in this spindle for a tool at the time with this machine. So when I calculate the min limit, I'm effectively putting the spindle with no tool in it, about 25 thou from the table. Yes, Homing is just es

Re: [Emc-users] Parallel Port

I have done a fair bit of testing, and pins (1,14,16,17) work as inputs in X mode, they don't output any voltage in the other modes, but their resistance to ground does change in those modes, so something is happening. All the other pins seem to work fine. My loadrt line in hal is : loadrt hal_

Re: [Emc-users] Where can I get absolute, reference z home=0 z position?

Hi Gene, So, where do I get this absolute Z position to feed lincurve from? Assuming you have a cartesian machine joint.N.pos-fb is probably the way to go. That's what I used when I did something similar on my lathe. Les -
