MY MKS SBASE smoothie install

Here is the wiring diagram I put together that shows how my setup is wired to the SBASE. also here is my smoothie config file.

Config file has the following statements:

  1. stepper currents set to 0.6 for Y and 0.5 for X axis
  2. total laser power limited to 0.8
  3. Endstops setup to home to bottom left 0,0 ( I 3D printed a bracket to relocate my Y-Axis optical endstop.

Aside from your Y stops it’s pretty straight forward. Thanks a lot for this! are you using the original endstop but just relocated it? What does your custom bracket look like? (.stl?) :wink:

@Jon_Bruno I am using the original optical end stop. I suppose I could have gotten it to home to the bottom left by adjusting the config file, but I’m a mechanical Engineer so I went with the mechanical re-location lol. that way it worked like my 3D printers do.

I did not post the STL file for the bracket because even after printing it, I had a slight height issue, so I just took my heat-gun and softened the printed part so I could bend it by hand, then I held it in place until the material hardened back up again lol. I did not want to re-print the part

hah! heat gun adjustment… love it!.
I’ve done similar… especially if it’s a long print.
I had printed several copies of a custom intake manifold model for a project I was working on …14 hrs each print…little tweaks sometimes need to be made,

what firmware bin was used?
do you have it to share please?

6

@Damian_Trejtowicz I used the latest firmware BIN from the MKS SBASE GIT hub. https://github.com/makerbase-mks/MKS-SBASE

7

Im asking because i think ,only this firmware works with this board.i try newest from smoothie github and its not working with this board

8

@Damian_Trejtowicz yes I have experienced the same, I almost gave up on it because I could not figure out I needed the actual MKS Sbase BIN, but this is the price we paid for saving a little cash :wink: hind sight… I totally would have rather bought a legit Smoothie board for the wealth of open support I would have gotten.

All works now ,except on 100% power i get more like 28mA.i need set up max 60% of power ,how to lover this in config? Is pwm frequency(i have 200 ) need to be adjusted?

10

afaik laser_module_pwm_period should be set to 20… thats what Ive seen in examples before… I questioned the setting of 200 just the other day but haven’t had a response yet. But yes I also see 25+mA on 100% (watching)

@Damian_Trejtowicz in the config file you need to set max power there. mine is set to 0.8 so basically 80% max achievable power.

laser_module_maximum_power .8 # this is the maximum duty cycle that will be applied to the laser
