Misaligned engrave after cut

Machine: custom build, k40 some parts

Board: mini

Firmware: _Smoothie

Problem/ Question: _ok so, after a complete dissas2mble of k40 ive built a larger machine.
Im using 24v psu, external drives new bigger 17 motors and a cohesion.
Everithing seemed to be working fine until this.
I found that something is misaligning and dont know what…
Whwn i engrave the line fine till now, but when i go and fill the text inside everithing is pushed to left(front view)
See photos of the described above.
Hope this has a solution…
Double chexked connection, ok
Is there something 8n the config thqt is missing me?
Thanks all!


Hi Edgar,

Let’s take a look at your configuration settings since you have a larger machine. I also noticed on a prior post that you changed your external drivers to 1/8 step. Are they still set at that? If so, we may need to do some adjustments to account for that as well.

Please provide a copy of your configuration file for review. Copy and paste it in a reply with 3 backticks ``` above and below the content or paste the contents to Dropbox, Google Drive, or Pastebin and provide the link here.

hi thnks for reply i have set the drive to 16 microstep
here it is config.txt (25.3 KB)

hi there i think ive found the problem , the drives… i bought a pack of 3 for 15 20 bucks , and it seems they are lossing steps all of them…
i had som leadshine dm542 swap them and looks good the problem disapeared .
dont you think 3 new drives tb6600 style is strange to be all bad?

Hi Starla, problem is still here with other drives i tried engraving a picture and its loosing steps or something…
Have you checkrd my config file?

Hi Edgar,

I did look at your file. You mentioned the issue was resolved with the new drivers, so it seemed you did not need further assistance at the time.

There are a considerable amount of edits to your configuration file. Below are my observations and recommendations, many of which are covered in our Larger Laser Machine documentation, for reference:

  1. Lower your default feed rate, seek rate and acceleration, testing with incremental increases or decreases until fine tuned. There are also acceleration parameters at the axis level that could be lowered, but start with the global one first. Your alpha and beta acceleration values are set to 30000, so they could also be decreased.

    default_feed_rate                            1500             # Default rate ( mm/minute ) for G1/G2/G3 moves
    default_seek_rate                            12000            # Default rate ( mm/minute ) for G0 moves
    acceleration                                 1000             # Acceleration in mm/second/second.
    
  2. Your steps per mm seem relatively low for your X and Y axis. Are your pulleys a 20 tooth count?

  3. If you do a simple square test that is 100mm x 100mm, at a slow speed like 25 mm/s, are you getting a square that measures this exactly in the output? Use digital calipers to check.

    alpha_steps_per_mm 80 # Steps per mm for alpha stepper alpha_steps_per_mm 157.575 # Steps per mm for alpha stepper
    beta_steps_per_mm 80 # Steps per mm for beta stepper beta_steps_per_mm 157.575 # Steps per mm for beta stepper
    
  4. The microseconds_per_step_pulse has been set to 1. It should be defaulted to 2. Try changing this and see if it helps.

    microseconds_per_step_pulse                  2                # Duration of step pulses to stepper drivers, in microseconds
    
  5. Decrease your max speeds, testing with incremental increases or decreases until fine tuned.

    x_axis_max_speed                             12000            # mm/min
    y_axis_max_speed                             12000            # mm/min
    

Start with these edits and if you still continue to have issues, let me know.

Thanks Starla ill try and get back with feedback.
Now im also positive sure it as to be settings not the drives.

Hi there tried those settings but no sucess problem is still here
I have 20 theet pulleys and it cut exactly the size i want…

Hi Edgar,

How fast are your running your file? Double click to open the layer settings and provide screenshots (no cell phone pics, please) of the entire LightBurn window for the file you are working with, please.

Great, that means your steps per mm are dialed in nicely.

Also, look at the specs on both of your DM542 and TB6600 external drivers. Check the microseconds_per_step_pulse again. We may need to bump the value higher than 2. I’m finding some models of the DM542 with specs of 2.5 to 4.5 µs. According to the Smoothie site: Actual step pulse is generally 2 µs above this (so 1 will actually be 2-3 µs). Setting this over about 8 µs will cause severe issues with step generation. It’s worth testing.

hi here it is first i was triyng to engrave at 400mm and lower to 250 , to 200 i would say with better results at 200mm/sec.
ive aso read the docs on the dm 442,so i changed the value to 3microsec, not so good results.
lowered all the feed rate and seek , max speeds to very low setting.
should i try higher settings on the microstep? docs say it should be higher than,2.5msec
thanks

ha and one thing to mention is , when engraving this picture at some point it loooks like it misses some steps because it misaligns , but if i stop the machine and it play again it goes back to the begginning with no loose steps.~
basicly it starts where it should start …
i dont know if i made miself clear. sorry im not english :grinning:

Im only getting this on photo engravings, if i fill some text or shape draw in lightburn everything is good till now.

Hi Edgar,

Lowering the speed is a great step to take. Once you get it calibrated to your liking, you can do some tests to figure out how fast you can push your machine before it starts skipping.

Since the Smoothie site states that a setting of 1 is equal to 2-3 µs, setting it at 2 like I originally recommended should be fine for your model. That should put you at 3-4 µs, which is higher (as your doc recommends), but still well below the max amount mentioned.

To confirm, you also tried lowering your alpha and beta acceleration values in the configuration file?

Skipping steps could also be caused if your current is not set high enough on the drivers, potentially causing the motors to not produce the needed torque to operate properly. Double check the current rating for the Nema 17 stepper motor specs and set your DIP switches according to the current table on the DM542 drivers. Try increasing it slightly, but make sure your motors do not get hot to the touch. Check your specific model, but here is an example for reference:

Hi acellaration is set to 200 max.
Hi have enough torque i tried to stop the motor with my fingers no sucess!

Is there a specific reason you needed the external drivers? Nema 17 stepper motors can typically run directly connected to the board with the onboard drivers.

You’ll want to start looking for potential mechanical issues.

hi starla , thanks for help, ive been reading about clustering firmware , ive tried and it helped a lot , i dont have photo scanning like in a start and stop motion.
my nema 17 are not original they are bigger and they need 2.5 amps , i just dont know if its peak or rms either way i think those trinamic drives are not up to the current.

Thanks for the additional info. I updated the response to remove those test steps.

Did you reflash the SD card with the new firmware.bin file and enable Cluster in LightBurn?
