How are delta movements calculated?

There are two main special steps to the technique used by most open-source 3d printer controllers: Divide each linear gcode segment into lots of very small subsegments ("Segmentation") Use some basic ...

How to change the voltage on a FLSUN QQ

I don't know if this is the case with all FLSUN QQ printers, but mine was indeed set to 220v as the instructions/user manual indicated. First I needed to remove the bottom of the printer. Then there ...

Why not use high rpm stepper motors with high microstepping with gear reduction in 3D printer?

To answer each point: Microstepping improves resolution as much as 32 fold (I think) but reduces torque the higher you micro-step. Torque is not reduced by micro-stepping. Torque reduction only ...

Nozzle moves very slowly from home to start position

I had the same problem, and I solved it by changing the Z-Axis Feed Rate to a much higher value (1000 mm/min.) in Repetier Host via Config -> Printer Settings -> Printer.

Kossel accumulates error along Z axis

After some more testing I checked that the problem shows up only on Z tower and is not related with current. Examining the tower I found very dumb mistake. Pulley on the motor didn't have a setscrew! ...

At which point does a delta 3d printer change the G-code in order to work in its non-cartesian design?

The short answer is that the handling of the non-cartesian design is done by the motion-control firmware running on the Arduino. The long answer: I don't believe GRBL supports non-cartesian designs, ...

Delta Printer: Slighty incorrect print alignment on the build plate

I figured out that the reason is probably a slightly translated slider construction. Instead of using a proper centered slider as shown in red, I used a slider construction like illustrated in yellow. ...

Why are delta bots so finicky?

user77232's points are valid but I have done several things to mitigate these issues on my Anycubic Deltas. First, both of my deltas have linear slide bearings. If your's has the bearing trucks that ...

Bed leveling method not working with Repetier firmware 0.92.9?

As a guess, you are using the wrong command. If set for n x n grid, you get 3 point measurement with G29, but that is not auto leveling, it is just setting Z height - based on average height at 3 ...

Delta 3D printer extruder?

My FLSUN Kossel 3D Delta printer ($224) has a bowden extruder. It works really well too. The main advantage of having one is that it reduces the mass of the hot end. That means less inertia, and it's ...

Scaling/size issues in delta printers

Issues in X-Y size on a Delta are usually the result of an incorrect diagonal rod value in the firmware. This should be easy to fix assuming the rods were built together. The formula for this is (...

Printer going wild mid print

For anyone having the same issue I found out it was due to a Z axis motor lock up because the pulley attached to it would get stuck under the bed. I found out because I tried to print again and it ...

Where to find z coordinate in G-code for delta printer

It isn't hidden at all. It's just that the Z-axis position only changes with each layer change, so the Z coordinate is only passed at layer change. On line 17 of your example G-code, it starts the ...

Getting wrong measurements on my Kossel Linear Plus after installing SKR 1.3 with Marlin 2.0

So the problem was that the TMC2208 were wired for UART mode, yet Marlin was configured for standalone, which apparently makes them work, but with completely wrong step sizes. Changing it in the ...

0.9° motors for Delta printers?

Delta bots always need all motors to step to maintain a straight level. Microstepping, is not magic, the incremental torque decreases per step so that you will be more likely to miss a few micro-steps....
