The following is a compilation of the input from a number of sources. Linear rails in general are mechanical components that - when designing equipment - offer great flexibility. The profile of the rail can be designed in nearly infinite ways. This in turn allows for: Different levels of stiffness in different directions (for example you may have stresses ...

A .hex file is of no use to you, because it consists of compiled firmware which is very difficult to edit. You need to go to Prusa's GitHub and download the source code. Then, find the header file for your model of printer, and change Z_max_pos to the correct value. Finally, you need to compile and upload the firmware to your printer following the build ...

You should be able to adapt the "Dual X Carriage" feature for your project. That allows a second print head (on the X axis) to move independently of the "main" X axis motor - and it can also be homed against its own endstop. You can enable this feature in the configuration_adv.h file under "Dual X Carriage". By default, all "Dual X/Y/Z axis" features use ...

Once you pull the plug or disable power to the stepper motors, the printer forgets its location. That is perfectly normal and exactly how it is supposed to work. The printer knows where the printer volume is once you have "homed" the printer. Homing is done prior to printing with G-code G28 which should be present in your start G-code script of ...

The direction of the end stop is set in the firmware of the printer. Even with different setup end stops, you should be able to get a correct coordinate system without mirroring axes in slicers. This would be the preferred method to fix your problem! E.g. my Ultimaker 3 Extended homes the Z on Z max having the platform at the bottom of the machine, a ...

One aspect of having this level of control with 3d printing of a model is the removal of the need for supports and the attendant post-processing. In the case of the model shown in the video, some effects are created by printing the continents in a conformal manner that would otherwise be impossible with conventional 3d printing. Cosmetically, the results of ...

I would try Googling your specific make of the i3. For example if you have a Geeetech Prusa i3. I would type in Google "Geeetech prusa i3 stl parts" and I'm sure you should fine plenty of things. If that is unsuccessfull. I guess try this one. It looks similar but it lacks that hole on the bottom middle to the right of the motor holes. So if its not ...

You should see MAX endstops similarly as MIN endstops, or as an additional option to protect the printer: Similarly seen as MIN endstops, you would define in the firmware that you are using them to set a reference point at maximum values, your offsets and bed dimensions would be calculated from the MAX positions; You can configure the MIN endstops and have ...

I shook off my laziness and disassembled the mounts holding the stepper motors and tightened the belts. After doing so the drift was resolved.

I found many ways to re-task extruder steppers to behave like cartesian-like controls: If your application does not require contemporary movement of all axes, you can enable multiple extruders setting the EXTRUDERS define in Marlin's Configuration.h. Then you can select which extruders will be set as E variable in G1 commands, by sending T0, T1 and so on. ...

Please check connections to the Y stepper first. You could replace cable from 'X' axis to test the connection. The noise from stepper mostly means a disconnected pin (broken connection), an obstacle on the path (check and clean if any) and a worse-case-scenario a broken stepper driver, so you could swap steppers (just by connecting the cable) to see where ...

I have experienced this a few times, usually this is related to the end stops. If your end stops are somehow triggered (e.g. short circuit or cable broken; depending on the setup), the steppers will not home (as they think they are at the limits already) and only advance forward. Please look into the end stops of X and Y. Use a multi-meter to measure them ...

I think that you probably need to adjust the following two parameters in the Marlin firmware, in configuration.h: MANUAL_HOME_Z_POS, and; DELTA_SMOOTH_ROD_OFFSET See my answer to Delta printer nozzle not moving square with a perfectly level bed (as if the bed is bent... but it isn't).

Do your belt goes Sproing when playing it with a finger (actually it doesn't really need to make a noise, but it should be somehow reasonable quite tight). If not, tighten the belt. Try with lower speed, for example, it is usually hard to start off with 60mm/s or more. Try 40mm/s or 30mm/s for starters. Up the current on your drivers! You do this by turning ...

The two most common things to check: 1) make sure your belts are properly tensioned. If there's significant slippage in the y-drive you could get the results seen. 2) Make sure the base layer is well attached to the base plate. you've got plenty of reference pattern on the plate shown, so check whether the lower chunk of print moved relative to the ...

Slicing prints for printing in 5 Axis is not going to be simple with the current software. If you look at the web site for the 5AxisMaker you can see they are using Algorithmic modeling software (Grasshopper). You would probably need to buy this as well and then spend a decent amount of time learning how to use this software as well if you were going to try ...

Well, in my particular case, it helps to have the X and Y control (motor and endstop switch) plugged in to the correct ports :-( . That took care of the X vs. Y orientation problem. If you command "Home All" either via the LCD panel or over USB, the nozzle should sit in the front left corner of the bed as you face the machine ("stage right" for you ...
