Couple of things... If you add a slave axis in your conf wizards, it'll add the second motor and you only need to dial in the motion parameters of the single joint. Slave axes don't require separate joint/axis settings, just the stepgen pins and possibly a directon reversal in the case of mirrored rack and pinion drives There's a special flag in the ini file called no_force_homing = 1 that you can enable to skip homing the machine before you move stuff Hope this helps.
Just wanted to add a comment to let people know that they should check out the LinuxCNC Bare Bones series at your channel. It adds a lot of additional information to go along with what Brian has presented.
Brian, thank you for the follow-up video and especially for sharing your files. This will really help a lot of people to at least have a decent starting point. One question that came to mind is related to the micro-stepping value you're using since it will affect some of the values in your files. Hoges suggested using 1/5 stepping, which is what I was going to start with. If you're using a different value though it would make the settings off a bit. Can you let us know what your micro-stepping value is on your motor drivers?
@@ProjectsbyBrian Ok, thanks. I think the micro stepping is a compromise between torque and accuracy. So I'm guessing 1/5 is the right balance that he arrived at while making this CNC. Definitely going to go with what the creator uses.
Hi Brian. We (me and my father) are making a first PrintNC in Azerbaijan :-). We are trying to make a right choice between LinuxCNC and Planet CNC. The second one looks more attractive and user friendly with many and many beautiful bonuses (API for an external apps and etc). But It is not free (145 EUR for hardware + 85 EUR for software license). My final question is: Is It right choice to go to the Planet CNC ecosystem (and always be dependent on one manufacturer) or choice Linux CNC, as the most pragmatic choice for the future? We want to make one choice and work 3-5 years without thoughts about electronics or software.
@@ProjectsbyBrian Hi Brian. I want to say thank you for such quick and informative answer/opinion. We a trying to focus on what we will produce on PrintNC, and we need, as you mentioned, a turn key solution. So Planet CNC looks good for us. Brian, thank you for such incredible PrintNC machine. You're genius.
@@ali_mammadov I'd like to interject and say that when converting from Mach 3, I was able to have my machine back up and running in a couple of hours without any help or guidance. Now, I could configure the exact same machine in 20 minutes, including installation of the operating system. The beauty of LinuxCNC is the flexibility down to a source code level, but there is a small learning curve for the amount of power the system provides, which is why I started my series of tutorial videos. They've already helped a lot of people. 👍👍

@@ProjectsbyBrian no problem. Linuxcnc is kinda what I do in my spare time 😆

@@gizmobowen Its how I got my lathe and Mill running. Just confused about the tool changers for Mori Seiki lathes.
I'm not quite at this point yet but when I am I'm coming back and rewatching! Keep making all the great videos!
You are the best, brian!
Could you possibly make a video about how do you probe ? What probe do you use, or how exactly does it work ? Thanks !

Nice job!
Can you make a video about offset setting on Linux CNC?
Another really informative video, great job!
