Are you using a RIP or a installed version of linuxcnc?

Sorry didnt mean to post the ini as a reply

ok

Tried a third cable this morning with similar results.

cornholio,
Thanks for the kind offer, I will send a PM.

John.

edit:
Well, PMs don't work.
How can we get in touch ?

John.

Can you post your current hal and ini files?

Thank you for being willing to try to help me, I also looked in the pins and didn't find anything, I also looked in the documentation to see if there was anything that could be added to the ini for this, but to no avail.

Take a look at the ini file spindle section,
MAX_OUTPUT and OUTPUT_SCALE parameters

2.6 stuff should work "as is" on 2.7 as the only major change i can think of back then was the new trajectory planner and look-ahead.

Just spent 10 minutes sifting through existing pins, could not find something useful, sorry.
I am pretty sure there must be something...

So, The hardware portion of my minimonster (datron wannabe) mill is ready, and I now need to lay out the control "for real".

First up, I need to decide on the system. I want to stay with linuxcnc at this point for cost and flexibility, and with renewed work on jerk control it seems like a good plan. Anything "better" would add several thousand to the machine and lock me into their system.

So, lets see what we need

1: axis drives. Planning on using Delta B3 drives. There are pulse versions, and then there are ethercat versions. Is ethercat in linuxcnc at a stage where it "just works" yet? Can it read an absolute encoder to remove the need for homing? Related: what lower cost options are there for ethercat IO?

2: spindle drive. Is there a way to track rpm/bogging down at the control lever on a spindle with no encoder? Maybe something optical? Do we gain anything by not using tradition analogue control? I think the drive has modbus/rs485 (delta ms300).

3: ATC magazine. My atc will be spin by a small 24v ac servo. I expect I would run it as an axis, but I need some safety and inteligence. Anyone ever implement a system that not only check the mag position, but also actively knows if a tool is in it? Is this something best done in an MCU than then sends out more simple responses to linuxcnc?

4: Active chatter control. Anyone got any thoughts one this? The principle is you bond an accelerometer to the spindle nose, and if chatter builds up, you can respond in several ways. 1 is to pause the program. Another is to modulate feeds or spindle speeds. Superficially seems an easy feature to add but I have never seen it done yet.

5: 3d tool measuring. I am looking at a little laser tool setter and it can in theory measure both the length and the diam of the cutter. Do the available probing cycles in linuxcnc/probe basic allow for such a thing?

6: Limit swapping. My ATC and tool setter live outside the cutting volume. We had the same issue on the brothers. Did someone figure out a simple easy way to "switch envelopes"? Move soft limits, ignore limit switches etc?

That's kinda the core of what I'd like that I am unsure of right now. Any thoughts on any of these are welcome. The rest is relatively straight forward.

 

Some clips of the prototype version running if you haven't already seen them.

I think there's a problem here. According to qt_action.py. TOUCHOFF_SUBPROGRAM = PATH.TOUCHOFF_SUBPROGRAM. If I print this path to the console from the handler, it shows Touchoff routine at /usr/lib/python/qtvcp/lib/touchoff_subprogram.py. However, there's no such path on my machine. It should be python3. BTW, TOUCHOFF_SUBPROGRAM is not mentioned in the PATH section of the qtvcp libraries documentation.

Can someone help me get my AC servo working as a spindle in Pncconf?  I’ve so far been able to set the port as an Axis StepGen and then I’m able to jog the motor perfectly and test it out but when I attempt to set the port as a Spindle StepGen I can’t get any rotation.  I have also connected the encoder signal wires from the drive to the encoder port and I’m successfully receiving encoder data.  I can’t seem to go any further now to making the system work though.  I’ve also tried setting the encoder into differential mode and single ended mode of which both are displaying feedback data but still can’t rotate.  Is there something I’m clearly doing wrong?   Any assistance would be greatly appreciated.  Thanks

I do not have the .ini or hal files onhand as the lathe has not arrived yet, however, I believe sherline has it posted on their website here: sherline.com/wp-content/uploads/2016/04/...027070277.1718319041

I do think that I will end up just trying to get it to run on a later version of linuxcnc, perhaps I will try downloading 2.7 first to check it out

I haven't been around enough to know 2.6 but 2.7 is available at linuxcnc.org/iso as an iso. Might try that?

It shouldn't be that hard to get it running on 2.9.2 instead of 2.6.
Do you have the ini and hal files?

Good evening my friends, I wanted to know if there is any way to make the axis interface open with the feed and the rapid at 0, I didn't find any documentation about this, I'm wanting to make a slightly different machine and I had this need, can anyone help me, Alves has to edit the Axis interface, I'm not sure, thanks in advance.
