It is compatible with GRBL V1.0, Benbox as well as mDraw. It’s why I was looking to see whether grbl for the MKS DLC V2.0 had an open drain configuration option, and didn’t see it. MKS Gen V2.0 DLC GRBL Controller - Makerbase Product Description This is the control board from Makerbase, it is based off of the 328P chip from Atmel, it is a 3 axis control board with the ability to power a DC motor or 12V Laser diode directly from the board. It also has to invert them that’s the ! in the configuration. That’s why the config files on the cohesion3d page links to shows the o modifier for all the ports that’s how you tell smoothieware to use open drain configuration. Note that this is “open drain” configuration.
So all that 5V power supply is doing is lighting up as many as 12 LEDs at once.īasically, this is a really fancy arduino “blinky” sketch with 12 LEDs that are hidden from view! The LED is turned on by connecting the port to GND, and the current is limited by the resistor of the opto-isolator to a level that doesn’t hurt the chip. GRBL OFFLINE controller Makerbase MKS DLC v2 control panel cnc plate MKS TFT35 3018CNC Pro. Each of the three lines to each of the four stepper drivers is “opto-isolated” meaning that you are driving an LED inside a package, and the high-voltage (motor) side then uses a photodiode to tell whether the LED is lit. 0+MKS TFT32 5 A4988 Drive Features: The 2560 and for ramps1. You are basically just driving an LED for each of the 12 lines. Mks Dlc V2.0 Endstop Upgrade To MKS Press question mrk to learn th rest of th keyboard shortcuts Lg in sign up User account mnu 1 BLTouch issue after upgrade to MKS SGEN-L V.2.0 on Ender 5.When I remove the cable from the ENDSTOP Z MIN on the Board, Marlin detect BlTouch malfunction, so I guess it is working fine. You can share the same 5V supply for all 4 stepper drivers, yes.
