PSA bad endstops! - 4 months ago

Sadly I don't recall where I got these makerbot clone endstop board from. The top image is what I received, the bottom is what they should look like. Due to them not matching standard physical layout I never attempted to use them on anything till now. Now that I designed something to use them, I tried them, only to find they do not work.. They short vcc to gnd!! The issue is that switch t

Re: Dual Z and Y axis and end stops on Ramps 1.4 - Merlin 1.1.9 - 4 months ago

You have #define EXTRUDERS 1, not 0 This tells marlin you have a E0 axis On a modern marlin bugfix 2.1.x you can definitely remove E0 On positively ancient Marlin 1.1.9? this is unlikely to work without a lot of code changes

Re: Dual Z and Y axis and end stops on Ramps 1.4 - Merlin 1.1.9 - 4 months ago

RAMPS has 5 stepper drivers total You seem to be trying to setup 1 * X 2 * Y 2 * Z 1 * E that is 6 stepper drivers, one more than you have

Re: Independently, Manually Controlling Dual Axes - 4 months ago

You cannot have axis Z1, Z2 etc this will break things badly Gcode is space independent so if you sent a G1Z120 did you mean move Z to 120 or move Z1 to 20, there is no way to tell. This is also why we don't have E0,E1 etc, but only E with the T gcode to change the tool

Re: WIKI Clean up - 4 months ago

Only a few get to edit the main pages, as to many attempt to change the wiki to their personal advertising platform Your creation of https://reprap.org/wiki/Discontinued_Models and edits https://reprap.org/wiki/Build_a_RepRap is in my view an example of just that, where by your pushing the printers you like to the front of the queue Most of these are not even what I would call reprap, they are

there is no such thing as 2.1.2.3, net yet anyways You give almost no information. no config, not much to go on. Auto fans are not visible. You cannot control them, so they are not on the display

Re: Compiling Marlin 2.1-3.x firmware - 4 months ago

there is no such thing as bug fix-2.1-4.x yet. "error: missing binary operator before token "("" is caused by miss matched versions. Latest bugfix does not have macros EITHER or BOTH, and the config file your trying to use has these Start again Download Marlin bugfix 2.1.x either with git clone https://github.com/MarlinFirmware/Marlin.git or download the zip https://github.com/MarlinFir

Re: Z axis compensation problem with BLtouch - 4 months ago

The way to activate bed leveling is different depending on what bed leveling they enabled Most are G29, but Unified bed leveling is more complicated Try this test via pronterface G28; Home all axes G29; Probe the bed M420 Z10; set z leveling fade height, this may say unknown gcode G1 Z3; Move to Z = 3mm then watch your flags and do G1 X200 Y200 ; replace the numbers with the size of y

Re: Z axis compensation problem with BLtouch - 4 months ago

if your bed it relatively flat and level, it is difficult to see any Z movement Add a flag to to top of the Z so that you can see any movement easily. (a bit of tape woks fine)

Re: update stops at 100% - 5 months ago

2.1.2.2 is severely broken! Enabling input shaping on that version of marlin makes the controller reboot over and over.

Re: Stepper motor 0.9° vs 1.8° - 5 months ago

Don't bother with 0.9's unless you have a delta 3d printer For other printers it just doubles the number of steps it needs and halves the maximum speed

Re: Tevoup Tarantula Pro Firmware - 5 months ago

Re: MKS Robin Nano V1.2 Input Shaping LCD reboot loop? - 6 months ago

2.1.2.2 is a bit of a lemon dont use it with input shaping, or a probe in the probe port that needs a pullup (ie bltouch and clones) List of known 2.1.2.2 bugs, some have patches

Re: RAMPS 1.4 and external mosfets - 6 months ago

@ChileMaker how about some pictures of the mosfet modules and where all the wires actually go? the MK52 is about 1ohm so pulls about 12 amps, most external mosfets should be able to do that easily This doesn't really make sense from the description... The connection form D8 to the module is just the on/off signal, it has practically no current. It normally goes to a optocoupler so is just t

Re: Bambu Slicer 3MF to Prusa Slicer - 6 months ago

3mf should just be zipped text files, so at least in theory you can examine it and perhaps write a converter. But who knows what they did to it... Closed source sucks!. But basically at this time there is no fix, other than repainting Start simple, take a 20x20x20 cube, colour each face a different colour make them identical in both Prusa slicer and Bambu Slicer, compare the 3mf archives.

Re: MULTI_VOLUME on SKR Mini E3 V3 - 6 months ago

That is not MULTI_VOLUME, That is for if the controller has a sdcard and a usb flash drive port, which your board does not have. You just want to use build environment env: STM32G0B1RE_btt_xfer Which sets up the firmware to allow you to upload firmware to the sdcard over usb cable via binary file transfer. There is no support for 2 sdcards if that is what your trying
