Thanks for your review.. I have heat sinks and two fans installed, one blowing directly down on the board and one blowing across the board as I have 3D printed a stand that suspends my tingG controller up 1 1/2" in my enclosure so I don't believe heat is an issue. As far as tweaking the currents, I did try that after reading through this thread and did some more testing but still encountered the drifting. I am hoping Alden makes 426.02 available soon as I have a few jobs backed up waiting to be milled. I will try 380.08 again with the build 3009 of tgFX see if that helps.
Will you be building the hex file and making it available on your download site, I have attempted to build it from the DEV branch but I am running into issue loading the new build on my tinyG, I am sure it is something with my building of the file..
well everything seemed to be working good until the third pass on the roughing stage where the Z Axis seems to loose its mind and took a deep dive into the wood. I have tried using the generic gcode Post Processor and the tinyG mm Post Porcessor with the same results. When running the gcode for the roughing phase i get through two passes then on the third pass it starts out ok but then the Z Axis dives down the depth of the material, .75" and I kill the job.
Let me run this with coolterm to make sure it's not on the board itself. An axis losing it's mind points to a communications error, but I'd like to rule out everything else. Can you air-cut this with coolterm? Use Con/Xoff for flow control.
...and sorry if you have already said this, but what are you using to send the file, and what communications settings are you using - flow control, etc.
Also, how big is your work area? Mine hits the edge. I have an old Shapeoko.
Yah I would like to know where we are "losing it at". I will run your gcode tomorrow. Can you describe the fail? Its always are to see what "should be happening".
We typically can isolate if this is a issue with tgFX or TinyG in general by having you run this though coolterm >> via send file (make sure CTS is enabled). If it still messes up then its a TinyG issue. If not then its a tgFX issue.
Sorry you are having issues and lets get some solid data to help get you working!
Hello Alden I am using tgFX build 3256 and am using RTS/CTS I also tried with JCNC also set to RTS/CTS and both parameters for connection were the same set at Baudrate 115200, Data Bits 8, Parity NONE, Stop Bits 1.
I am using a shapeoko 2 with a work area of 11.25" x 11.25", I will run through coolterm today to see if i can determine where in the gcode it is failing and report back.
Thanks guys for all the help it is much appreciated, I am able to execute very simple jobs that only include profile tool paths but when i get into 2.5D roughing and finishing tool paths that is where I see issues.
I am loving tinyG and tgFX and if we can get this resolved I will be in CNC Bliss...
The issue happens at line 4193 when it starts to make the cut for the barrel edge design. It is running on coolterm now just waiting for it to get to that area of failure.
I finished running a test on coolterm and it fails in the same spot with the same issue in that the Z Axis is sent down through the wood which looks to be a bit deeper that the overall depth setting of .75 inches now that i look at it a bit more..
If there is anything else needed please let me know...
Regards,
John
