Hi Dust, Thank you for your suggestion. After changing fpos_t to fposition with a new version, it seemed compile, then it did not upload. I had to change the arduino board and the cable. It had been 2 years since I stopped printing, and I was surprised how quickly and how much I forgot. I am at the ground zero. Now I am struggling with x-axis home function: when I hit 'home x' the carriage fliesby photo444 - Prusa i3 and variants
I have bought and put together it in 2017, and I was happy for its performance. A problem occurred recently when I upgraded the computer: Arduino did not compile even I have updated all the required software. Did anyone have the same issue?

My printer is a new creature all together with the motor upgrade! Before the upgrade, when I hit 'home', the three carriages were barely hanging at the home position after hitting the limit switches, but now they are firmly locked at the home position. Prints are clean and nice with straight walls, and it seems doing what it supposed to do. I highly recommend upgrading motors with higher capacitby photo444 - Delta Machines
The motors were barely warm at 0.65V so didn't bother to lower them. It seems better practice keeping them as low as possible. I will try that. I also have 2020 i3 there I tried to lower them to be 0.35V and no troubles. I will certainly check the top bearing of the troubled axis. I think it also is a good idea to check the driver boards by swapping, too. I wish I had all the good suggestionsby photo444 - Delta Machines
Paul_delta, Thank you for the reply. I have checked the vRef and they are ~0.65V. Only Z-axis motor is bad (along the '-y direction' on the bed), and other axes are 'OK' compare to the Z-axis. The behavior is consistent with that the Z-motor is not strong enough to push the carriage back to where it has to be. When the motion is limited near the center the effect is minimal, but when the strby photo444 - Delta Machines
I do need serious help for my printer. When everything is reset, it prints well. But when the printer is continuously used, layer deposition is shifted to one side as shown in the picture. This problem goes away when the machine is reset. Is it possibly caused by the controller? Or some mechanical problems? The attached picture was taken in the morning when the printing was left unattended durby photo444 - Delta Machines
I have been enjoying reading posts of this forum and thanking all of contributors. Recently I have finished building a rev B printer and having fun with it. After careful measurements and calibration a 20mm cube was printed for testing. As shown in the attached picture, the cube is not straight but tilt along Y axis. I have found that the radius value is slightly different between the three aby photo444 - Delta Machines

The center to center distance should be 18 mm. Could you please draw STL file once more for me? The overall size can be little larger perhaps by 1 mm. Here is the piece 18mm and 19mm between centers. let me know which oneby photo444 - Prusa i3 and variants

Hi Markts, For simple change of X-axis direction, I moved the limit sensor to the LEFT side, then on the RAMP1.4 board the stepper connector was turned around 180 degrees. This requires NO changes in the programming parameters. I used the test prints in the thingiverse. Good luck!by photo444 - Prusa i3 and variants
