So I am in the process or reverse engineering some of the SnapMaker components so I can use a different controller with them. As I figure out how things are wired I am going to edit this post with that info. 3D Printing Module: PIN1: VCC, Heater Socket Pin 1, Fan+ PIN2: Stepper Coil A+ PIN3: Hea…

As I don’t have a Snapmaker yet, I’m not entirely clear - is the RJ45 cabling on the Linear Modules embedded, or detatchable? If they were the latter, a broken cable would mean you just replace that, not the whole component.

Hello CthulhuLabs, Thank you on sharing these pinouts. I can confirm that a nominal 81K is measurable between pins 7 and 5 of the RJ45 jack. And the absence of a sensible value, ie open circuit/short circuit between pins 7 & 5 would have the snapmaker controller halt proceedings. On an other where…

Did a full Tear Down and Compared to actual servo motor wiring. This is from the wiring method used on the extruder motor and also how the servo’s are wired. I built TL Smoother’s and the Diodes need to be on the + side which is 2 & 3 For the Linear Module: Slight Modification. PIN1: Coil B- …

The laser module (200mW and 1600mW) pin 1: +24V pin 3: (inverse) Enable, PWM input pin 5: 130 Ohm resistor to GND as module identification pin 7: GND pin 2,4,6,8: N.C. I found on internet this schematic . The driver uses a XLSEMI XL3005E1 laser driver IC. Snapmaker uses almost the same circuit …

Hi I also want to use the SM1 for other purpose and make a XY table to extend my 69W fiberlaser galvo system , I already have a controller that a pulse and direction outputs for two stepper units . What controller do you want to use . Best Regards Lars

Great information! I am going to modify my 200mW laser module. Want to build a handheld laser welding tool to weld plastic parts together.

Hi CthulhuLabs Did you succeed to adapt another controller (A Uno preferable running GRBL 1.1f) to control the linear module . If not GRBL controller may I ask what controller did you use All best Lars

Here’s what I came up with, got the linear module working this way with an Uno and a CNC shield. Too bad the shield only had 3 axes, which made it unsuitable for snapmaker. Will try some day with my bigtreetech to see how fare we get :slight_smile: [snapmaker wiring]
