CoreXY Calibration Issue
Oscar's answer is the correct solution to this issue. My printer was printing skewed and there is a built in correction for this in Marlin. Unfortunately the X5S does not have a boot loader and I don'...

CoreXY Calibration Issue
Indeed, even belt tension is important, what helped me enormously to set the same tension in the belts on my self build CoreXY is a tool like this:
Furthermore, be sure that you do not have any ...

CoreXY Carriage moves on the Y when moving the X
For a CoreXY printer to move an axis (X or Y) it requires both stepper motors to turn. If both turn the same direction (at the same speed with the same pulleys), the X-axis will move, if they rotate ...

Tronxy X5S losing steps during print
I had the same issue with my X5S when I first got it assembled. Because it's CoreXY, if one pulley slips, you'll skip steps in the diagonal. Check both set screws on your pulleys for the X and Y.

Configure Marlin for tool changing system
Use a servo. This way you can use the digital pins to control it; or in your specific case PWM_PC9
Connect it to the expansion port and configure one of the digital ...

CraftBot XL (CoreXY) part of x-axis movement resistance / high force required
I'm going to answer this myself, as I believe I have found the issue. It was purely a mechanical issue.
On this particular model, the extruder motor rides just on top of / above the crossbar that the ...

How does an H-bot printer work?
The CoreXY kinematics can be seen as an evolution of the H-bot kinematics. In Marlin, you both need to configure the printer as a CoreXY machine. Note that your steps are determined by the pulleys in ...

Which kinematic system has the highest quality?
The tradeoffs in these systems are all about quality achievable at particular speed and acceleration profiles. If you really don't care about speed at all and want maximum accuracy, you probably want ...

How to start a print in the center position after a change in parameters using M92 and M500 G-code
Every time I.m will go to print, if turn off the machine, the process to be need repeat, in other words, the gcode M500 doesn't work.
This tells me that your firmware has the EEPROM support needed ...

How center the nozzle before start printing
You have defined your bed incorrectly in the firmware.
First line you print is at X=2, while it is printed a couple of centimeters from the edge. Second the final cube is not in the center of the bed ...

Is it normal for belt tension to differ between sides of a CoreXY printer?
If you are referring to the tension in a single belt, but ar different positions, the tension is everywhere the same. It is one belt, the force/tension is the same in the belt. If the length of the ...

Problems with X axis movement
After many hours tinkering, pulling things apart, testing them and re-assembling them, it turned out that the problem was a broken wire for the X_Min endstop. This has now been replaced and the ...

Layer Shift with a new CoreXY printer
Shifts in a diagonal direction in CoreXY indicate loss of synch between the two belts.
If it's the belt very loose skipping, you may not hear much but such a loose belt is easy to notice.
If it's the ...

Do I need linear rails on a corexy printer's z-axis while already having quality lead screws at hand?
Using rails for Z is overkill. They are stiffer than smooth rods, but for Z axis that's not needed.
Using only the leadscrew may be enough, especially in designs with three of them, but if you have ...

CoreXY with 8 bit board problems
CoreXY should not require calculations which can slow down a board. Also, a normal Marlin becomes CPU limited often before 100 mm/s on 8 bit boards due to arc interpolation and other processing.
