I just done a calibration cube print to check my sizes. With the default steps per unit of 80 for x and y and a A4988 stepper, my cube was too small by roughly 4mm! (Anet A8 SKR 1.3) Before I switched to this board and Marlin 2.0 bugfix, my default for the Anet was 100 on x and y.
If you calibration cube was 20 mm cube, multiply by 5 in each measured axis. For example if x axis is 16 mm, multiply by 5, giving 80 and then divide by 80 and then multiply by 100. You new value for x axis will be 100 and no longer 80. So the formula will be (actual/current) * 100 = new current. Reload modified Marlin firmware number and upload firmware, then reprint and remeasure. The value should be closer to 20mm.
@@qwertzbalken6076 What if we are using dual extrusion head ? Means that both of my E0 and E1 pins are being used. Where can i attach my second z-axis motor? Thanks in advance!
@@abdulbasitrana2465 You could use a y-splitter for the Z-axis (So a Single driver controlls both stepper Motors) but I'm not sure if your stepper driver can handle that. You probably need a low pitch lead screw so the forces are not to high.
Thank you so much for the video. There is one problem I have been stuck with for days now, Pronterface shows the "STOP called because of BLTouch error." I have searched the web a lot, but power cycling didn't work. Anybody who had this error please help...
Besides the use with a RepRap/3d Printer, what else can the MKS Gen L V1.0 be used for? Can any stepper driver (ex. L6474) be used with the software/hardware? I've read people using the DRV8825 (45V 1/32 microsteps) instead of the A4988 (35V 1/16 microsteps)!
You can use many types of stepper drivers. The new versions of Marlin firmware have upwards of more than a dozen stepper types. Keep in mind the datasheet for each type and the current limitations of the MKS Gen L board. The MKS Gen L could be used for a CNC machine or laser cutter. I've not covered lasers due to lasers light and possible damage to the eyes.
@@EdwardBraiman No it moves the same direction. I changed the microcontrollers to the A4988 and now it is working, but with the tmc2130 on Standalone there is only one direction of movement towards the endstop. I also tried to adjust the Voltage on the TMC2130 but there isnt any voltage.
You could check for the JGAurorawiki A5 upgrading stepper motors, that printer uses the MKS Gen L Board, and requires a firmware upgrade before enabling "smooth motion"
He was using TMC on a video designed for A4988, the jumper configuration might be different, but it's been ages since I've done a tutorial on this board. I'd need to check.
@@EdwardBraiman I bought the Mks Gen L V2.1. I was wondering if it could be used (Tevo Tarantula) without adding A4988 drivers or any other drivers. Just the bare board. I can't find any info Anywhere how to set it up without the extra (A4988) drivers
@@Bill.Lockhart-Laser-3D Not sure I understnad question. You want to use a MKS 2.1 in a Tevo Tarantula without a populated board? You might want to watch more tutorials in playlist first. The link is in description to playlist.
This is the kind of information I needed. And explained in a manner that does not assume I'm already a board designer. Thank you!
You're welcome.
Very helpful - thank you!
You're welcome.

Very clear, thank you. I’ll have to see if you have a video about adding two z motors to that board.
You activate dual Z-Motors in the Marlin Config and Connect the second Motor to E1 and add a second driver too. Done.

Try it out with a card type MKS Ronin Nano35
Computer did not recognize USB it using arduino
where is the problem ?
Thanks
My Steppers are only moving in one direction and the endstops are all connected and thanks for everything
What happens when you home the axes? Will it then move in the other direction?
@@EdwardBraiman No it moves the same direction. I changed the microcontrollers to the A4988 and now it is working, but with the tmc2130 on Standalone there is only one direction of movement towards the endstop. I also tried to adjust the Voltage on the TMC2130 but there isnt any voltage.

Yup.
