Ok I got it to work. Kind of. It still is a pain zeroing out everything. It is very buggy. and will lose zero. But as you see below one of my axis is set up backwards. It is supposed to read “Dana” Does anyone know an easy fix for this?
Sounds like the y axis is configured wrong on the TinyG. What settings did you configured it with? There’s a tinyg config floating around this group somewhere. But it may need modification depending on how you wired up your motors.
$2po=1
$3po=1
assuming you used motors 2 and 3 for the Y-axis.
@Colin_Kaminski yes I did. I will try this in the morning. Thank you again. Hopefully cncjs will zero out without any problems.
Getting closer! You might want to start with some simple gcode by hand. No cutting.
Home, then zero your WCS work. Then command “G1 X10”. It should move to the right.
Check Y axis code also. Then you’ll know if it wasn’t a setup option in Vcarve (it has options that will flip etc).
@Jeb_Campbell thank you. I will check that also.
That’s a good point Jeb, in Fusion I have to set the WCS (work coordinate system) to match my table. As convention I chose to use the near, top, left corner as home. I must make sure that the G-Code generator also does this.
Building and wiring a 3d printer was cake compared to this, but it was a good learning experience that a cnc router builds on.
Subtractive manufacturing is more complicated than I thought it would be, but as I learn more, I can see the history behind it. Just imagine writing all that gcode by hand… And to simulate it, you had to run the machine.
@Edward_Bigham – keep at it! You’ll get it figured out. I got stumped on those capacitors / limit switches / homing and was about to pull my hair out. Sometimes you have to take baby steps and eliminate causes. Write some simple gcode that you understand (we can help) and see if the machine goes where you think it should.
I also spent lots of time jogging the machine around sorting things out. I had a bunch of 2x4s laying around that got cut up into guitar neck shapes while I learned the basics. While I am now happy with my TinyG and Chillipepper the idea of running off a RPi and no internet is appealing. I use RPis for everything and having a desktop in the shop is hard to keep clean.
@Colin_Kaminski CNCjs runs without internet so I highly recommend you look into that. It is missing a few features that Chillipeppr has (autolevel being the only significant thing thats actually useful), but it is a simpler interface if you ask me and is a lot more stable. I have my raspberry pi setup to host it.
@Jeb_Campbell I figure after the weekend I will have a good grasp on everything with it. I just don’t like machines being smarter than me.
@Colin_Kaminski the whole idea was to have a program that I don’t need internet also I didn’t want rpi to have another thing that can go wrong.
@Edward_Bigham the best realization I had when working with these things was actually they’re incredibly dumb. Treat them like a child, repeat everything 3 times and get them to read it back to you before you say ‘ok go do it’. Double and triple check every action, make yourself a checklist of things to do before hitting play!
I got it homing correctly.The only problem is when i home Z it drops down about 5mm then picks it up. Any ideas?
I had an issue with mine doing this as well. I don’t remember if it was a “reverse the output” option in TinyG that I changed, or if I flipped the wires going into the TinyG. The more I think about it, I believe it was software. Someplace you can change the output/direction.
@Corey_Perez Changing the wires makes the motor run in the opposite direction. It will pick it up then try to zero going down.
sorry. I was referring to the “backwards” wording. I think my “X” was backwards on my initial setup.
If you are homing your z, and it drops, it is reversed. I just seen a video/post about this in the recent past…
I am 90% sure it was a software setting… UGH! Sorry. I will see if my memory comes back. (I hit my head, HARD long ago, and don’t remember things like I did)
@Corey_Perez Right now when I home it it will start off going down then it stops and picks it up all the way to the home position.
