For now yes that is correct. we have a branch we are working on with a database type tool table which will allow for many more functional options and usable tool parameters to be stored and called upon during subroutines. one of those parameters will be tool storage so it knows which tools are storable in the atc and which are not etc. there will be some really awesome updates coming with the tool database updates.

There are 3 active forums at the same time, and as far as i can tell, they are all replicated (meaning the content is copied from one to others automatically):
The one we are using
forum.linuxcnc.org
The one on the same server but in a different folder
www.forum.linuxcnc.org
And another one with no domain name, just the IP address with no secure connection active
162.243.45.186
That is also on the Digital Ocean servers
www.whois.com/whois/162.243.45.186
The first two are for sure on the same virtual servers, so updating one impacts the other, the third might or might not also be on the same virtual server, there is no way of knowing from my point of view.

I've been working with FreeCAD for quite a lot of years on hobby project, It's OK-ish, and even though you can do amazing thnigs with it, it's not my favourite program.

I used FreeCAD 1.0 for a quite elaborate self made drawong of a CNC milling machine I've been working on (of and on) for 4+ years now, and with all changes I make on the drawing it becomes slower. This is now to a point that it's starting to annoy while working on that drawing. Loading time of the drawing changed from around 30s in FreeCAD V0.22 (just a few months ago, nearly the same drawing) to over two minutes in FreeCAD V1.0. Apparently this has something to do with the way the topological naming thing was "fixed", but at the moment I'm regretting working on that drawing in V1.0. I'm thinking about reverting to a backup and redo the changes I made in an older 0.22.

I also have one very big drawing, which is 7 drawings of CNC machines imported in the same drawing to compare them, and even in FreeCAD 0.xx that drawing takes over 5 minutes just to load. That would go towards half an hour just to start FreeCAD if this trend continues. Go figure.

smc.collins:

I spent 20 minutes trying to sketch a simple part to revolve and gave up after the autoconstraint engine completely hosed up the sketch. They really really need to put work into the sketcher and the UIX

I find the sketcher in FreeCAD quite nice. Like everything in FreeCAD, things could be done quicker and with less mouse clicks, but overall the sketcher is quite functional. It is also easy to mess up in the sketcher. It took me quite a while to learn what sort of constructs to avoid in the sketcher. As a general rule, build up the sketch in small increments, and do not have to many unconstrained items. You can't expect to learn a tool such as FreeCAD's sketcher in 20 minutes.


 

I have been busy the last few days.



It looks like IRQ coalescing is disabled by default.

Just reinstalled ethtool.
No error message so far.

Just waiting to see if the error appears at random.

A few days ago I read in the manual this should be possible, You once do some measurements and create a table, and then you enter that table in LinuxCNC's setup. "lead screw compensation" (ball screw, or rack & pinion, or whatever is all the same for the software) is apparently a special case, you do not need customized kinematics because it's built into each axis.

I'm planning on experimenting with this. My idea is to add a glass scale temporarily along each of the ball spindles, and have a microcontroller measure the position at set intervals. Partly to check accuracy of cheap chinese spindles, and if LinuxCNC can add some correction, that's even better.

But I do wonder about your big deviantions. 2mm is a lot. I suspect your machine has mechanical issues.

When I log in I see this message but I don't feel comfortable running that command.

Normally you get better answers on a forum if you show you've put in some effort yourself, and then ask more specific questions.

You can start by reading about Kinematics in LinuxCNC

linuxcnc.org/docs/2.8/html/motion/kinematics.html

In short: You write your custom kinematics in C, and "halcompile" compiles it into something compatible with LinuxCNC.
