A quick question: is it OK to add Turn G-code (commercial, with a free 15-day trial) to the CAM table on the wiki Cam page (wiki.linuxcnc.org/cgi-bin/wiki.pl?Cam), next to CamBam / Estlcam / SheetCam? If yes, could someone PM me the wiki password? Thanks.

It hasn't been clear to me about the resistors:

What value should the resistors have and what power should they dissipate?
4.7 ohm and 1/2 W resistors would be okay?
And I understand that they must be connected between the 5V pin of 7i97T and the QA, QB and IDX pins.
 

470 Ohms 1/4W  would be a good value (~10 mA) 
(4.7 Ohms is way too low = ~ 1A)

I am a new user of a few months with linuxCNC and AXIS and  found a resource of several Python scripts to use in Axis but many of them failed to work as most where created many years ago and not for use in Python3 so I fiddled and tweaked until they did then I enhanced some and created some others for my own use to save having to go to CAD to make toolpaths and run from a button on the sidebar in Axis.

Would these be of any interest I am willing to share (not knowing how to is an issue ). ADMIN...Unsure if this is the correct place to post this if not please let me know and either move to somewhere else or delete. 

More functions have since been added

They go back to the controller, you are swapping the controller, so they go to Mesa now.

Thanks for responding.

I wasn't planning to touch the cables between the driver and the encoder, they have 16 or 17 cables.

yes, hal pins need to be connected but reading/sending values over modbus come before that. got that working and then also hal pins went quickly and easy

just a little detail in case somebody else will encounter this in the future:
Correct value of "First element" for first register is 0, thanks to Ralph Stirling for sharing a working config.
Attached is working ini and hal files for mb2hal and Invertek Optidrive E3
 

I have to agree with Todd, such machine is much more versatile with two separate controls.
A nice local network with a NAS would also add a lot to functionality and ease of use.

At one point in the past I was getting quotes for buying a double router like that. In the end our company decided it was more cost effective and practical to simply buy two separate machines.

Es ermöglicht die erfolgreiche Nachrüstung älterer Maschinen —z. B. kompletter Homag-Holzbearbeitungszentren mit mehreren Tischzonen— unter Verwendung von LinuxCNC.
Ich bin mir ziemlich sicher, dass dies bereits möglich ist, siehe G55, G56 usw.
 

 

I am indeed referring to a multi-channel control system.
The machine works on a component on the left machining table, while the next part can be set up on the right table simultaneously. Once setup is complete, the program is started and the table moves to a standby position. Only when the left-hand part is finished does the machining head move to the right to execute that program. At the same time, the left table moves out of the machining area to a parking position for re-setup.
There are also multi-head systems, and so on.

We have all flavors of Amish here. From ones like you describe to Swartzentruber Amish that will only use a couple kerosene lanterns on their buggies (they won't even use a smv triangle.) The ones like you describe may have a 50kw (or bigger) genset for their wood shop to run big CNC routers and other wood working equipment, but those wires run to the English city; das ist veboten.

Servus, thanks for your message, nice to meet another Austrian here!

I’m originally from the Amstetten area, but Salzburg is also home for me. I went to HTL in Steyr, and I’ve been self-employed for around 20 years, mainly working in the aerospace and automotive industries.

My background is primarily in PLC programming, CNC machining and industrial automation. Over the years I’ve worked on pretty much everything around metalworking: mechanical engineering, machine automation, fixtures and clamping systems, CNC programming, commissioning, and of course complete machine retrofits.

I also started working with LinuxCNC very early on and was one of the first to use it seriously for machining centers rather than just simpler hobby machines. That experience is actually one of the reasons why I’m now pushing the multi-channel system further, I see a lot of potential for bringing older but mechanically excellent industrial machines back to life.

Your Homag example is interesting as well. Multi-channel control could definitely open up a lot of possibilities for machines with several working areas, tables or independently coordinated processes.

Has anybody got G95 working with their remora setups??

iv got it working by setting lowpass-spindle-encoder-velocity.gain to true.

But how do I permanently set it to true. I tried setp in .Hal but it's getting overwritten every time I restart linuxcnc

I understand, in that case you can delete it. If some customer posts a question in future in a different thread, I will reply, but no more promotion and I'm also grateful for the opportunity the forum provided. We really wish we could go open source. We will at least make some of the larger suite of products open source. Our target is to make engineering software of all kind extremely affordable.

Do not delete your replies, that is really, really not polite.
If you do need to edit it, leave the original content, unless it poses a risk/danger, and add the corrections/additions/etc.
