It can be both firmware or your slicer. firstly there is probably an outline on your bed that shows exactly where the 200x200 limit is, locate your 0,0 position Put z down to about 1mm and home x and y send the printer a G90, this sets the printer to absolute positioning Then send a G1 X0 Y0, this moves the printer to location 0,0 (it may not move at all) If its now not at 0,0 this is a hardwby Dust - General Mendel Topics
An io pin can only drive 5v and at very low current. Most fans are higher voltage, I also wouldn’t want to drain all that current threw the micro It has nothing directly related to speed control. (That's PWM, a feature of some IO pins) Most fans people have are 12v. A mosfet is used when you need to control a device that needs higher current or voltages than an IO pin can handle.

You can use any IO pin, but you cant use it directly. And yes using X_MAX_PIN should be fine You must use a mosfet on the pin to actually control the fan power.by Dust - General
For uploading to work a boot loader must be installed on the device. Depending one what boot loader is used it will use different baud rates and settings. (baud rate is completely independent of reprap firmware, defined in boards.txt) And it may not have a boot loader at all. What board type did you set in the arduino ide? What type of cpu is even on that board (no details on it that I can fby Dust - Reprappers

What are you using as a dc motor controller? as it depends on what signals its expecting. This is what we used to use A3949 H-bridge motor drivers so there may still be some legacy code about to control these..

take a look in your pins.h MOTHERBOARD 33 doesn’t normally have more than one fan defined.by Dust - Firmware - mainstream and related support
wall thicknesses of 0.127mm is not easily achievable... and defiantly not via software magic. you would need a phisical nozzle with a hole of a little less than that diameter To force plastic threw that tiny hole you would need and extruder with a lot of torque (ie a geared extruder, preferable strong metal gears) Direct extruders are a joke for this sort of thing.

Yes its really that simple, 3 control lines and a gnd "I always thought the planner would need specific pins to synchronize the steps-output?" in a perfect world you want the step pin on the same port as the other step pins so they can all be activated with one 8 bit io write. In reality It doesnt matter NB E0 step pin is on D26 (PA4) and E1 step pin is on D36 (PC1) Ie they are already onby Dust - RAMPS Electronics

At a guess you have the eeprom enabled and have not updated that If you use M500 even once then from that point on you must update setting with further M500's.

This means that your machine is actually working. I suspect the gcode is waiting for a bed temperature before heating hot end. gcode is just text, open it up, have a read search for M140 (set bed temp and accept more input) also search for M190 (this also set the bed temp, but will wait till the Temperature is achieved) also find out where you M104 command are, after or before M190's Ideaby Dust - CoreXY Machines
Do you have power to both the 11amp 12v and 5amp 12v power plugs on the ramps? so if you send a "M104 S190" does the D10 led turn on? Does the hot end temp increase? Second led in from the left top cornerby Dust - CoreXY Machines

Gen7 has no support for a LCD, so unsurprisingly no pin definitions have been setup for it. If your trying to hack on the GLCD you going to have to create your own pins.h file Personally I wouldn’t bother... GLCD's use to much rom (all the fonts have to be stored in there, as well as the graphics data) and when running it uses to many cpu cycles, causing blobs in your print.

according to this mostly Chinese pdf Those pins are just always on 12 or 24 volt. This would make sense as you should never turn off the fan that blows across your hot end cooling fins Now if you want an additional cooling fan that software can control plug that into the D9 port.by Dust - Reprappers
