GRBL CONTROLLER SOURCE CODE SERIAL
GRBL CONTROLLER SOURCE CODE SOFTWARE

The firmware is no longer being developed by MKS and they have released the source code, but it is a hashed up version of the 3d printer firmware again and well beyond my abilitiesвЂ¦ InterestingвЂ¦but no cigar! The mere fact that editing these screens and legends are beyond my expertise left me feeling it wasnвЂ™t worth proceeding with the screen. The laser would, however, work fine from my 2% button in the вЂSettingsвЂ™ page, this macro sent M3 S2 so I wonder if the open/close icon omits the Sxxx and the 'home button has the Sxxx. It appears as though there was no comms over the Tx/Rx, even after reboot, even after a reboot without the USB connected, the only way I could get GRBL unlocked was to fire up LaserGRBL and issue the $X from there (or do a homing from LaserGRBL), after that the display commands seemed to work.ДЄlso had some issues in getting the laser to fire up using the Open/Close icon on the first page, even after setting the power to be >0 - it would only work after resetting 0.0 with the вЂLocaliseвЂ™ button followed by selecting the вЂHomeвЂ™ button. Incidentally, I did end up a couple of times where the display would not unlock GRBL with the $X button.

My guess is that these TFTs will work with any board running GRBL that has a serial header on it. The TFTs have icons for homing, setting home, axis movement, spindle/LASER ON/OFF, spindle speed/LASER power, relative feed rate(%), SDcard file access, and also has slots for custom commands you can add by editing the config before loading the firmware to the TFTs. Remember, these are MKS TFTs, not BTT TFTs. Now Makerbase makes two other TFTs that support the CNC firmware. And, if you thought ahead to avoid ruining the VR on your cheap MEGA2560 and removed the D1 from your RAMPS board, you will have to supply 5V to that as well through USB or otherwise. Since the CNCshield sources 5V from the USB, you would have to use the USB as a power source, or connect 5V to the board another way. Now I think the RAMPS stack has multiple assignable serial ports, so that may work. Doing so causes random, unexpected comm errors and will usually cause your running job to fail.

You can have it plugged in, but not have any software connected to the COM port. You would connect to the 5V and GND, and the TX/RX pins on the header above the end-stop header.ДЇrom what I have experienced, when using the TFT, you cannot have the USB COM connection in use on a connected computer because they share the serial line. You need to either make a custom cable, or just use 2x2, or 4x1 Dupont cables. You cannot use this cable to connect to the CNCshield board due to the different pinout. The TFT connects to the DLC and the RAMPS boards to AUX1 via an 8pin ribbon cable.
