Re: Assigning pins for custom buttons, What Have I missed? - 5 months ago

Look at the circuit diagram PE6 -> SN74LVC1G17 to level shift the voltage from 3.3 to 5v -> RGB pin There is no way to use the RGB pin as a input due to this buffer

Re: Problema asse Y - 6 months ago

A common misconception. That SPI (or UART) connection for stepper drivers is used for moves, it is for configuration and monitoring only not for moves. Movement uses the standard enable, step and direction pins, and these are directly connected to the atmega2560 IO pins Yes, it is very likely your arduino mega has a damaged atmega2560 chip

Re: Hotend stops heating at around 40 degree celcius - 6 months ago

You cannot generate 24V 10A from a power supply with 12V 8A Power is fixed 12v 8A = 96watts so 96watts at 24v = 4A amps. (assuming perfect conversion) but you only need 1.66A at 24V for a 40watt heater cartridge, so this should work.

Re: Ender3 v4.2.7 BIQU v2 microprobe setup? - 6 months ago

The trick is it needs a pullup, the probe port does not have the required pullup. use the z-stop pin for the trigger. Ie this warning displayed by Marlin #warning "BIQU MicroProbe V2 detect signal requires a strong pull-up. Some processors have weak internal pull-up capabilities, so we recommended connecting MicroProbe SIGNAL / GND to Z-MIN / Z-STOP instead of the dedicated PROBE port." Marl

Re: Hotend stops heating at around 40 degree celcius - 6 months ago

Prusa Mk3S has 24v volt components including the hotend heater cartridge the ramps is 12v. this will not work together. The Cooling Fan 5015 50x50x15mm from the Prusa mk3s is 5v so you cannot plug that into any of the ramps mosfets either, they all run at 12v. There are hacks you can do to change a ramps to 24v Or get yourself a 40watt 12v heater cartridge

Re: Marlin and endstop setting - 6 months ago

Sensorless homing is marketing BS In reality the tmc stepper driver has a pin (diag) that is connected to the endstop pin that triggers when the stepper detects a lack of movement. (like when it hit the end of travel) // // Trinamic Stallguard pins // #define X_DIAG_PIN PC1 // X-STOP #define Y_DIAG_PIN PC3 // Y-STOP #define Z_DIAG_PIN

Re: How to Increase the maximum temperature setting in Marlin - 6 months ago

You need to find the line "#define TEMP_SENSOR_0 1" In Your Configuration.h file The 1 means your using type 1 thermistor You need to get a better thermistor You need to install that thermistor You need to update #define TEMP_SENSOR_0 1 and replace the 1 with the new number that represents your thermistor type. (see ) for the list Once you have updated the value you then need to compile Mar

Re: How to Increase the maximum temperature setting in Marlin - 6 months ago

You need to use a thermistor type that can handle it You have set thermistor to type 1 for TEMP_SENSOR_0, this thermistor has a absolute max temperature of 320C also the firmware requires a HOTEND_OVERSHOOT this is set to 15 (don't change this without understanding why it is needed and the consequences) So the highest HEATER_0_MAXTEMP you can set with that thermistor is 320 - 15 ie 305C You

Re: Opinion on 24AWG for hotend - 6 months ago

" Most Chinese boards are closed source." this is over stating things MKS and Bigtree Tech are both Chinese companies and provide circuit diagrams for most of their stuff. From a previous post PCLoadPLA said you have a Artillery Sidewinder X1 which has a BOARD_MKS_GEN_L which has circuit diagrams

Re: Turning off Heated print Bed - 6 months ago

@SirPaz Look at your temperature on power on, use M105 If this is not reading a sane value (ie close to room temperature) The instant you attempt to set a temperature it will error. Also note that if the room temperature is actually really low < 5 degrees, the machine will also error. Most thermistor in Marlin are NTC, ie they follow this example graph To trigger a MIN TEMP error

Re: Panucatt Re Arm & BTT Mini 12864 V1 - 6 months ago

Your also going to have issues with lcd RGB_DIN pin, ie the neopixel back light, as that pin is not connected on the re-arm, you will need to connect it to an unused io pin. and telll the firmware where it is connected

Re: Panucatt Re Arm & BTT Mini 12864 V1 - 6 months ago

no. See the 5v pin on exp1 of the lcd, you connect that to 5v, because on the re-arm with a ramps and lcd adapter exp1 port is 3,3v Here are the exp1 and exp2 pins when on the rearm this is why re-arm comes with special cable eg

You don't change anything in platformio.ini except default_envs restore the stock one You have to open up the directory with the platformio.ini file in it, not the marlin sub folder Vscode is multi platform... you dont need a vm, but if you feel you must setup ubuntu 22.04, way less overhead than windows. you really need to have the code on a local hard-drive, not networked

Re: Non-integer steps per mm - 7 months ago

I will add a note. This should only be done if your gantry moves an incorrect distance Printing out something and measuring it is not a good way to get an accurate steps/mm, only a rough estimate. Incorrect E or Z steps/mm will mess this up, as will a number of other settings or plastic shrinkage

Re: Non-integer steps per mm - 7 months ago

Ie your talking about DEFAULT_AXIS_STEPS_PER_UNIT used in code like this xyze_float_t default_steps = DEFAULT_AXIS_STEPS_PER_UNIT Ie the steps are floats, that is numbers that have decimal places This is fine, and common practice. example from standard configs { 80.08, 80.17, 400, 101.30 } { 80, 80, 100, 97.5 } { 76.190476, 76.190476, 1600, 164 }
