Re: step size, bed size for RAMPS + A4988 - 4 days ago

3200 should be correct but it is is a lot of steps / mm for a old 8 bit controller. I would definitely change it to 1/8 micro stepping and set 1600 steps/mm you will need to reduce the X and Y DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 } // X,Y,Z E See how Z is way slower, because Z is a lead screw (or threaded rod)

Re: Prnter wont print circles just ovals - 6 days ago

Can also be caused by the printer X and Y axis not being at right angles to each other Print the outline of a square, measure both diagonal corner to corners. If the measurements are not the same the axis are not at right angles to each other

Re: Auto home thinks midway on each axis is home - 7 days ago

Check your endstops Use M119 while you manually trigger the endstops with a finger Endstop should report OPEN when not triggered and TRIGGERED when it is triggered I suspect yours is backwards If they are then you need to invert them #define X_MIN_ENDSTOP_INVERTING false // Set to true to invert the logic of the endstop. #define Y_MIN_ENDSTOP_INVERTING false // Set to true to invert the log

Re: Marlin Input Shaping on Prusa? - 8 days ago

The first input shaping added to Marlin was deigned and tested on a 8 bit board. The issue is not all 8 bit boards are equal. IS takes quite a bit ram, It was designed on a atmega1284p which has 8 KB while the much more commonly used atmega2560 only has 4KB of ram You can run IS on a mega2560, but you have to reduce the max feed rates to reduce the amount of ram used. You also seem to be a li

Re: Creality 4.2.7 Problem - 10 days ago

Please define ignores If marlin does know the gcode it should tell you unknown gcode. If a G1 does work something is seriously wrong. The most common cause is if you installed firmware meant for a V4.2.7 controller on a V4.2.2 controller. It will not move, but otherwise behaves like normal.

Re: Pronterface s not connecting - 13 days ago

Serial ports are single connection points only. Ie you cannot have multiple things using the serial port at once. Make sure cura/vscode/arduiino ide etc are all closed before starting Pronterface. If its windows give the machine then reboot as windows likes to hold on to serial ports even after the program has ended.

Re: Creality 4.2.7 Problem - 15 days ago

When you change your extruder not only the probe offset changes, but the position of the hotend changes You need to update these. #define X_MIN_POS #define Y_MIN_POS #define X_MAX_POS #define Y_MAX_POS Sometimes this also makes it impossible to get the full distance of your bed and you need to update these also. #define X_BED_SIZE #define Y_BED_SIZE

Re: Mega 2560 with Ramps 1.6 and 128LCD - 19 days ago

Trial and error You set the values high in firmware The you use simple gcode eg G1 X100 F{number} You you back and forward trying larger numbers till it is no longer reliably moves. You then set slightly smaller number in the firmware.

Re: My first self made 3D printer presentation and ask for help - 21 days ago

1) steps/mm calculations includes micro stepping. From the values you have given you have no micro stepping. Under each stepper driver is 3 jumpers. these set the microstepping. For the DRV8825 the tables looks like this. If the jumper is on, this is a HIGH. Off is a LOW X and Y should be set to 1/16 microstepping Z most people set it to 1/8 microstepping 2) homing should be slower than prin

Re: Mega 2560 with Ramps 1.6 and 128LCD - 22 days ago

Problem 1: You have not updated #define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 } to fit your hardware. these are the max feedrates each axis can do on your hardware so you at the will of the previously set feedrate. If its to high, you buzz instead of moving. With these set the max feedrate is capped to the provided value. Problem 2: you don't just set those pins.. without se

Re: Ramps 1.4 with TMC2209 Stallguard? - 27 days ago

On ramps you need to remove all 3 micro stepping jumpers from the motherboard under each of the tmc2209 stepper drivers. (check with a multi meter that the jumper pins are not still connected with jumpers removed. At least some ramps have pcb tracks connecting the jumper pis so they are always 'on') You also need to power the board from 12v, powering form USB will also give you tmc error. The d

Are you sure you have a MKS_MINI_12864?, these are rather old displays They look like Are you sure its not a v3? This is a much more recent and common display and looks similar but is quite different in how it works. This is MKS_MINI_12864_V3 If by chance you really do have the v1 display this pins files should fix it

You need to update the steps per millimeter for E This is the last value in this lne #define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 400, 95 } According to the internet this should be 837 #define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 400, 837 } Important these values are stored in eeprom. they will not be updated until you reset the eprom to firmware defaults I highly recommend th
