We had people wanting to do something like this for plasma cutter and laser systems, back in the EMC1 days, and it was not very easy. So, HAL comes through again in making unusual options easy to accomplish! Kudos to John Kasunich! Jon - This SF.net email is sponsored by: Splunk Inc.

Re: [Emc-users] Floating Z (solenoid on PCB Mill) Hal configuration
Thanks -- I imagine this will be helpful to anyone with a similar system. the only thing that comes to mind is that the time emc spends on the "Z" motion had better be long enough for the solenoid to completely lower -- does this take long on your machine, or does it snap right down to the right depth before you can blink?

[Emc-users] Floating Z (solenoid on PCB Mill) Hal configuration
In case anyone else has one of these PCB mills with the solenoid driven floating Z, I thought I would share my configuration changes. The premise I worked with was that if I could take the commanded Z position and convert it to a bit output to my solenoid relay I could use the standard drill and move codes with it. So I connected the Zpos-cmd and a constant "0" to a comparator and then routed that to the par-port. Now any commanded Z position 0 or greater results in the head up and any Z command less than 0 puts the head down. Here is what I did, let me know if it could use any adjustments, I am new to this hal thing. In stepper_inch.ini I added a line for my new hal file: HALFILE= solenoid_Z.hal My new hal file solenoid_Z.hal contains: loadrt blocks constant=1 comp=1 constant.0.value=0 newsig constcomp float linksp constcomp comp.0.in1 linksp Zpos-cmd comp0.in0 newsig discrete_Z bit linksp discrete_Z comp.0.out linksp discrete_Z parport.0.pin-07-out addf constant.0 servo-thread addf comp.0 servo-thread That's it. After a few syntax problems it worked. I am quite happy. Have fun, Tony - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
