This error appeared and continues to appear in versions 2.8.4 and 2.9.4 when executing G38.5. By tricking hal for version 2.8.4, the problem is partially solved.

It is impossible to verify that the problem has been solved in version 2.9.7 because a new error, “Queue is not empty after probing,” appears much more frequently in it (and in 2.9.4 as well) -

I already ordered a tube of Klüber LDS18, according to one of Rotary’s videos, this is the right stuff for the spindle.

It’s really unbelievably helpful to have resources from someone restoring the exact same lathe.

Mb2hal version didn't work great. I'm working on python hal component currently.
Meanwhile I made python app to drive FC01 inverter.

OK, so I can just do that and tell myself I’m not being lazy — it’s science. We’ll make an A/B test and see how the machines behave over the years.
Yes, that sounds like it could actually be a thing.

 

It is not difficult to pull the spindle. I just welded up a U frame to pull against and used all thread to draw it out. 
Schaublin recommended disolving Kluber in some solvent like trichchlorethane which we cant get. I don't yet know whether I screwed up good bearings or saved them. Time will tell. Starting over I would probably have just injected a little fresh grease. It is easy enough. 

If the dovetail fits, you could also just drill and tap the height adjuster holes on the other side.You can never have too many tool holders

I wonder why the replaced the X servo, but left the Z one?

 

I've added U and W to the G7x cycles, but those letters cannot be used outside the subroutine interpreted by those G7x codes.

Thanks ... that confirms what I suspected. I really hope the auto-tuning on the Delta B3 drives works better once they have the proper inertia of the machine. Running them completely without load probably doesn’t give the controller anything meaningful to work with.

I’ll revisit the tuning once everything is mounted mechanically. Fingers crossed that the B3’s auto-tune behaves more reasonably under real conditions.

The question about the grease in my head is that the spindle seems properly lubricated right now — no strange feeling, no signs of anything bad. So if I pull the spindle and put it back after installing the replacement belt, I’m hoping I won’t make it worse than it is. When it comes to regreasing these high-precision bearings, I’m hesitant — I’d rather learn on less costly spindles first.

Regarding Mach: the seller provided a copy of his Mach3 folder. I didn’t know this before, but you can just put that folder on the PC and it works—no installation, no configuration, no compiling anything custom.

I'm back home again, having been away at work during the week. I've created an initial config using pncconfig, then edited up the contents the best I can, based on my previous working instance in 2.8.4 Of course, those old files no longer work with the current version of gmoccapy and LinuxCNC, presumably due to changes that have occurred along the way, so I have no working system.

I'm in a bit of a Catch-22 situation, as I can't start from a working copy and simply(?) make a few changes. The SIM versions have a range of extra files to fool LinuxCNC to work without a real machine and I don't know which those are. My "starter file" created in pncconfig never got as far as being fully operational, not least because the bitfile in my 5i25 for isn't listed in the pncconfig options.

When I try to run LinuxCNC with my new embryonic config, it seems to bomb out when it tries to start gmoccapy. The debug info is very curt and doesn't seem to give me much of a clue what to look for.

I'm pretty certain I'm missing some of the files required for operation but I've no idea what those are. Without a functioning example, I can't work from a "known good" example. Ideally I'd have an example of a complete file / folder set that I can compare with - is there something I can refer to?

The various gmoccapy sims work fine but as I said, they seem to come with a variety of additional files that I won't need with a real machine. Can somebody help to identify which files I need and which I don't? Many thanks!

 
 
 

The aft-mounted one, I didn’t even think of that. I’ll try out tomorrow if it fits. It’s not just the wrong way around; there are no threads on the other side.

The servo is really much larger than needed, but buying a more suitable one when I already have this one on hand seems silly.
The controller is a CSMIO/IP-S

They seem to be sold on eBay for a decent price sometimes, so this might be the first retrofit in history that doesn’t cost more than expected (…it won’t).

To really run the thing I “only” have to replace the encoder belt on the spindle. If there’s one part I didn’t want to mess with, it’s the spindle — but I don’t think I have a choice here. I’ve seen some really bad belts, but never one that still worked despite having sections with no plastic left.

I’m considering just pulling the spindle and putting it right back in. What do you think? You replaced the grease without disassembling the bearings, right? Would you do it that way again?
