[Emc-users] mesa 7I43 + MPG + speed control rotary switch
Hello all, My father and I are trying to hook a MPG + a speed control rotary switch to a MESA 7i43 and it seems not to work as expected. The rotary switch has 4 position to control speed increment. We tried the configuration in PNCconf and we stumble into the following issues: * most of the time we have to manipulate the speed switch in order to have a change on the jog reflected in axis * most of the time we have to manipulate the jog switch in order to have a change on the speed switch reflected in axis It looks like both switch are somehow interdependent, we tried to tweak the debounce but with no success. Then we tried this while keeping all the physical connections in place: * Reconfigure just the MPG with PNCconf: every thing is working on 3 axis the motion switch behave as expected * Reconfigure just the speed control: changing the switch position correctly change the speed Do you have any clue to understand the issue we have when both the MPG and speed control switch are configured in PNCconf ?

Thanks for the bug report. A few questions: PNCconf has a few options that use MPG are you speaking of manual axis jogging? Same question on speed switch - do you mean manual axis jogging increments? if so, I use this same set up and seem not to have problems What version of linuxcnc are you using? eg 2.5 or 2.51 etc Could you post your .pncconf config file (not your actual config folder) Chris M -- Monitor your physical, virtual and cloud infrastructure from a single web console.

[Emc-users] 0-10V spindle control via Mesa 7i33
All- My Sieg KC4S lathe conversion is moving along, and I have a question about driving a spindle motor controller using a Mesa 7i33 servo controller. According to the docs, that daughter card uses sign/magnitude mode , which will generate 0 to +10V analog out when the direction is positive and 0 to -10 V analog. My problem is that the drive controller has a direction input and a speed input and the speed input is 0 to +10V regardless of direction. My thinking was that I could just tie the direction pin feeding to the 7i33 high and wire a different I/O pin to the direction input of the drive and tie that pin to the spindle direction. Unfortunately, I can't figure out how to tie the direction pin feeding the 7i33 to high. In the pncconf-generated configuration there is no explicit configuration that I can see tying the spindle direction to the direction pin expected by the 7i33. Am I missing something obvious or is there a different way to accomplish what I want? Thanks! Scott -- Monitor your physical, virtual and cloud infrastructure from a single web console.

Am I missing something obvious or is there a different way to accomplish what I want? Thanks! Scott The problem is linuxcnc does not have a pin that supplies absolute spindle speed. So you must run it through an absolute component and use the spindle cw signal. Do you use the spindle display options in PNCconf? If you do then depending if you use spindle feedback (encoder) or not there will be one of three signals available : No feedback: absolute-spindle-vel ( this is in RPM) encoder: spindle-fb-filtered-abs-rpm or spindle-fb-filtered-abs-rps The second two are filtered but I don't imagine that matters much. You would have to mess with the scale of the PWM gen to match input signal units and range. you would disconnect spindle-vel-cmd from the spindle PWM gen and connect one of those signals to the PWM gen. Then you can use spindle cw signal (selected in the mesa page) to select the direction on an available output pin. I think that should work if I didn't confuse you or me :) Chris M -- Monitor your physical, virtual and cloud infrastructure from a single web console.

Re: [Emc-users] linuxcnc 3 development whiteboard wiki page
Chris, I can't see the EDIT button on that Whiteboard. I have logged in etc but it remains Read-only. How about a simple simulation button? That's different from the Cutting simulation. I envisage the code running and the backplot window showing the result, without attempting to simulate the real workpiece. That would be a simulation in the single existing program, rather than a separately compiled simulation version of LinuxCNC. Click to run in simulation mode; click to run for real.

It would be best to add your two cents here so things are not forgotten and are all in one spot so we have a reference for discussion and planning. Feel free to add more headings. I think a short general statement as a minor heading then any details under it would be a good start - I added a few things in this way. Don't be afraid of adding your crazy idea - I'd rather see us pare down the list then wish we had thought of an idea earlier.

Everything was honoured except actual moment and I/O so no coolant or tool changes either. AFAIK AXIS already sorta does this behind the scene when you load a program. That's how it draws the picture and figures out out-of-bounds. Chris M -- Monitor your physical, virtual and cloud infrastructure from a single web console.

I think I've seen this sort of function called 'backplot' on machines I've used.
