Hi. I have read this from Ultimachine.com (developer of Einsy Rambo): "A preconfigured Marlin Firmware is preloaded onto the board. To re-flash this board, you can simply use the Arduino IDE with Rambo Addons and set board to "Rambo". There is an Arduino plugin folder on github that exposes additional pins in the Arduino IDE." I think I need to add this plugin to make the Einsy Rambo (or anyby serandre - Controllers
I downloaded the original COMPILED Prusa MK3 firmware and now the LCD WORKS !!!! There must be something with arduino that is causing this LCD issue with the source firmware.by serandre - Controllers
Hi. I have a fully working reprapdiscount lcd controller (tested on a MKS Gen 1.4). Now I bought a Einsy Rambo 1.1 board and the LCD only works works (without garbage) when the bootloard loads, or when updating the firmware (also the bootloader shows an animation while updating the firmware), but when the firmware itself loads all that shows on LCD is garbage.

UPDATE for this board: Dual filament printing using only one motor. Using the things bellow: and a filament y splitter in thingverse there're several of them. In the board there's a RX/TX/GND/5V connector, you can use the GND/5V and the Part cooling fan (PWM) to control the servo. In this case you will disable the part cooling (not need for ABS), but if using PLA or another filament that neeby serandre - Controllers

Ok nobody knows LOL. So I've done a math to get the convertion from RGB to M163 mix factor and also from CMY to M163. RGB to M163 mix =============== Example: RGB (240, 186, 173) Rv = R/256 = 0,9375 Gv = G/256 = 0,7265625 Bv = B/256 = 0,67578125 Tv = Rv+Gv+Bv = 2,33984375 Tf = 100 / Tv = 42,73 Rp = Rv * Tf = 40,05% Gp = Gv * Tf = 31,04% Bp = Bv * Tf = 28,87% In Marlin: M163 S0 P0.40 M163 S1by serandre - Firmware - Marlin
Does anyone knows how to convert a CMY color to the mix factor ? Example (Caucasian Skin color) C = 6 M = 27 Y = 32 K = 0 RGB equivalent: R=240, G=186, B=173 How to convert these values to a mix factor (when using the 3 filaments (CMY) in Diamond hotend) ?by serandre - Firmware - Marlin
I'm trying to write a code to select an extruder like bellow: int16_t lcd_filament_change_extruder; // I get this from user input on menu and them _lcd_user_gcode(PSTR("T" STRINGIFY(lcd_filament_change_extruder) "\n")); // all I get is a: Tlcd_filament_change_extruder out instead of a T0\n (or T1, T2, Tnumber).

I'm using the default for LCD_UPDATE_INTERVAL and DELTA_SEGMENTS_PER_SECOND, and no issue when printing curves. What print speed are you using ? Have you fixed the artifacts in your printing ?by serandre - Controllers
These are blobs and zits (https://www.simplify3d.com/support/print-quality-troubleshooting/#blobs-and-zits) issue. Make sure you have your extruder calibrate correctly.

Glad you have make it work. Just a tip: If you use the heat bed avoid to use it without a heat sink, my board mosfet has melted the solder after 6 months of use, use a heat sink on the heat bed mosfet (a large one that can fit in it) or use an external heat bed board, it's cheap from ML (about R$60), also use heat sink on the DRV8825's axes, this board only have heat sink on one DRV8825 chip (thby serandre - Controllers
Make sure you are using Marlin 1.1.7, I've tried version 1.1.8 and have several issues like these you had. Using version 1.1.7, before trying to do any home or auto calibration type the following command in pronterface or any slice software that allows issuing gcodes (make sure you move the carriages away from the endstop limit switches): M119 This command will show the endstop states: open orby serandre - Controllers

I have an issue trying to move the steppers bellow 0.1mm. My Delta printer is using 1/8o stepper motors with pulleys with 20t and 1/16 microstep drivers, so all steppers are using 80mm steps/unit in Marlin. If I try to move for example (I have tested with a dial indicator): G1 Zx.x5 It doesn't move. G1 Zx.x7 It moves, but for some reason it rounds to x.x+1 The command M114 shows the axis riby serandre - Mechanics
Hi. I need a substitute for a IRF1010NS. I'm using a heatbed 160mm, 12v, 120w in the printer. Which mosfet can I use to substitute this one (I can't find it in my country). Thank youby serandre - Controllers
GOT IT !!! I'm feeling so stupid !!! I was trying to move the X/Y motors before homing. So instead of homing (i was testing the board without the printer with just 1 motor connected) I just move the Z and all motors X/Y moved (it's configured as a Delta). So, mission completed. :-) Thank you for all the help I got from this board !!!by serandre - Controllers
Quoteo_lampe Did you try to home the printer ( G28 ) or sent G92 X0 Y0 Z0 to fake it is homed? Otherwise Marlin won't move XYZ axis. For the extruder you'd have to allow cold extrusion with M302 or heat up the hotend above ~170°C. Yes, I tried the G92 X0 Y0 Z0 and also the M302 S0 to allow cold extrusion. The Z and E works, but the X and Y didn't move to any direction, but if I try the M17 theby serandre - Controllers

More pins discovered for this board: #define HEATER_0_PIN 8 #define HEATER_BED_PIN 9 #define FAN_PIN 7 #define SDSS 53 So this has been completed, all pins discovered.
