Use something like Pronterface (or any other terminal) to connect to your board serial port via the USB connected to the PC (find your serial port, use 250000 as baud rate) and reset the EEPROM to defaults by issuing M502 and M500. This should take about 20 seconds (don’t quote me on that, it’s fast anyway).
Mks gen 1.4 dual axis update#
Connect the USB cable to a PC, this should start the update process, you should see the LED on the boads LED flashing.
Place the firmware.bin on the root of a SD Card and insert it into your new board. Head over to my MKS SGEN L GitHub repository and download the latest firware that starts with SGEN (all other are the official Marlin releases). If you don’t want to use the BLTouch or if you want to use it on a Sidewinder you will need to bake your own custom version. My printer is an Artillery Genius equiped with a BLTouch clone so the firmware is setup to work with that.
Mks gen 1.4 dual axis drivers#
You can now place the drivers in their dedicated slots on the mainboard and mount their heatsinks. move the driver voltage selection from 5V to 3.3V (orange).place jumpers on the X and Y DIAG slots (blue).place jumpers in front of each driver on the UART selection slots (green).all the jumpers underneath the drivers need to be removed (red).Board setupįirst things first, you need to setup the jumpers on the new board for the TMC2209 drivers in UUART mode and with sensorless homing. This will be especially useful in setting your BLTouch Z-Offset. Make sure you have plenty of space on your workbench and move the X gauntry up top so it stays out of the way.īefore you remove your old board, connect it to a terminal and save the output of your M503 so that you can later compare it with the defaults for the new board in case want to restore some of your old settings. A Dremel with a disk or a drill to make a hole for the SD Card slot. A pair of tweezers will help you remove some of the connectors and some IPA to get rid if the glue. If you don’t allready the Mako Precision Bit Set from iFixit is a must have and I cannot recommend it enough. So we will have to find a way around that if we still want to use the extruder LED.Īs for tools, you will need a number 2 allen key and a small flat screwdriver. You might notice they are almost the same except for the lack of Servo 2 ports and the AUX-2 and AUX-3 on the SGEN. The pins have different labels as the CPU is different and the labeling scheme is derived from that. Head yourself to the MakerBase GitHub pages and take a look at the layout of both boards:Įspecially the PIN files are important as they show you the pin layout of each board. It will make tracking all those wires much easier. I suggest you make or print yourself some sort of identification for your cables like the ones mentioned in the upgrades section. It will not cover the whole process in detail as it is a pretty straight forward replacement since the boards are almost identical and besides there are plenty of similar upgrade guides, instead I will focus on the key aspects specific to this board and drivers. This page will describe how you can upgrade your Artillery Genius (works for the Sidewinder also with small firmware changes) to a MKS SGEN L 32bit board and MKS TMC2209 V2.0 stepper motor drivers.
