Printing issues ...
Re: Shifted Layers with No Answers - 8 years ago
I wanted to thank everyone for their help with this problem. I figured it out last night! So after replacing nearly electronic, changing motors, wiring, firmware...it turned out to the the TB6560 that was the issue. I should have listened to all the other forums that complain about them. Even though I tried 3 different boards, they were all from the same manufacturer and so the problem was in theby chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
No the stepper motors have always been the TB6560. I have replaced the X axis twice with a new board and there has been no difference. I am looking at upgrading to a 2M542 The current board is:by chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
I tried to upload the new firmware to the board and I did not get any improvement from changing software. So I am not sure what I'm missing. I'm sure there is a simple setting that I have forgot about but I have yet to find it in the past two weeks. I have attached some pictures of the hardware that I am using. You can see the gear and rack as well as the TB6560 board that I am using. I again triby chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
After trying all of the above troubleshooting I had already done, I went ahead and replaced the entire ramps/arduino board with no change in results. The printer still is off the same amount and in the same direction. As of now I have: Adjusted Amperage Changed Stepper Drivers Changed Ramps/Arduino Adjusted Acceleration/Jerk Settings Slowed printer to a crawl (there is no difference printing aby chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
My travel speeds and infill speeds are both low (10-20mm/s). It isn't possible for the gear to jump teeth the way it is built. And because it is only happening in one axis makes no sense. Both axis are built the same! I've adjusted acceleration settings, jerk settings with no changeby chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
The weird part is that the X axis prints fine as long as there is no infill to the print. Just printing the perimeter there is no missed steps. Only doing the infill is there a problem. I think it would do it all the time if it was an amperage issue. I've also tried adjusting the current up and down with no change in print qualityby chevellebro1 - Printing

There are no belts, my machine uses rack and pinion. I have slid it by hand and it seems smooth to me. I've tried adjusting the gear and lubing everything with no difference. I tried swapping stepper motors yesterday with an interesting result. The missed steps caused the piece to slope to the right. However after swapping motors I realized that the motor was turning opposite of the other one. Soby chevellebro1 - Printing

I've swapped the driver, issue stays with the X axisby chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
I have the drivers in a computer tower with 120mm fans cooling them. And like I said all the other axis are fine. The Y axis and Z axis are both running 2 stepper motors a piece at 3.0A and are fine. For some reason the X axis driving a single motor is the one loosing steps. It doesn't make sense....by chevellebro1 - Printing
Re: Shifted Layers with No Answers - 8 years ago
I have adjusted it in both directions. The motors are NEMA 17 requiring 1.8A. I have adjusted the board to be lower at 1.6A and I've turned it all the way up to 3.0A to test. None of these made a different. It really stumps me because the motors and boards are the same for the other axis but it doesn't change no matter what settings or hardware things I changeby chevellebro1 - Printing

Shifted Layers with No Answers - 8 years ago
I built a new printer running Marlin firmware. I just started printing this last week and I have had little success at getting a good print. I started off with the calibration 20mm cube and that was problematic. I saw on another forum that someone printed a thin wall shell to start testing. So I started with this print and I had great results. I had the speeds very slow (20 mm/s) from the other cby chevellebro1 - Printing
Custom Lidar Endstop - 8 years ago
Hello, I am currently trying to configure my CNC machine to use a Lidar sensor as an endstop. What I am trying to do is figure out how to trigger the endstops once the distance has changed. That way the machine ZERO will be at the edge of the material. Thanks for your helpby chevellebro1 - Firmware - Marlin
