Problem: So when trying to do a corner probe with my v1 bit zero the machine lowers to get the z height, then instead of moving left, plunging and moving back right to get the x position it just immediately plunges again.
Guess: I’m guessing that the machine doesn’t think it has enough room to go left so it just plunges again. It doesn’t give any kind of warning about this .
Photo: the photo shows that there is some room for the bit to get left of the bit zero but maybe not enough. It also shows that I’m losing almost 2 inches in x travel.
Question: is there a way to reclaim some of this space? I think that would resolve my problem
I attempted adding 20 to my $130= value through MDI and even though the change was accepted, I reinitialized but the machine didn’t move more left
Open Carbide Create. In the Help menu select About. Then Open Data directory. Open the CarbideMotion6 directory and there are two .json files. json files are text files made in a certain format that Carbide Motion is able to read and it sets your jogging limits established during the machine configuration. Edit the Shapeoko.json file. The measurements are in MM. So you can increase any measurement you want but when the machine hits the mechanical stops you can loose steps. The constraints enforced by the .json file is what limits your ability to jog and the machine stops at the limits. However during running of gcode there is no limit and if you command with gcode to go way past the physical limits the Shapeoko will try to do so.
C3D has long limited jogging for a variety of reasons. Several years ago the SuckIt dust collection boot had ears that stuck out past the sides of the Z axis and so C3D limited jogging to keep you from slamming your dust boot into the side rails. To keep people from jogging to the mechanical stops is another reason they limit the jogging space so you dont hit the mechanical stops during jogging and cause your Shapeoko to lose steps and mess up your carves.
You can change the .json file with Notepad but just edit the text and leave everything else alone. The format and the other symbols in the file mean something to Carbide Motion. I would recommend you save a copy of the original Shapeoko.json file just in case things go wrong you can get back to operation. Also simply rerunning the configuration would restore a default .json file.
Ok, I tried editting the json but my stepper motor stopped working and started jittering. Ordered a new one so will try to continue this troubleshooting when it arrives. Thanks for the advice thus far
I disconnected the wire from the extension wire and didnt see anything unusual and I keep my wires in a cable wire carrier so dont expect anything to happened to the wire. Ill get into the controller board tomorrow and see if theres anything wrong there.
Ended up replacing the JST connectors on the stepper motor with ATX connectors so the connection is more secure. Old connectors seemed loose and also had a black burn point on it.
After getting it all back together, I edited the json and reclaimed the x travel that was missing before. Thanks for all the help.
