My bed length and width is 415mm but after getting everything going in the right direction when I command the printer to move to X115 Y115 it will travel to what should be 415mm.

@v-a-m-p-printing-snproj
Okay so I've been messing around with movement on my printer and notice the distance the printer head is moving is not correct. Before my maximum for the x and y was 415, but when i would try to go to X0 Y0 it could go to Y0. So I set the maximum to 115 for both the X and Y and now it can go to X0 Y0. Why is the distance my print head is traveling reading differently now?

@phaedrux Okay sounds good thanks!

@phaedrux Okay my only concern before starting a print is before i changed my drivers, in front of the rear lead screw it was reading that Y was at 85 and now it is reading at 315 at that lead screw. Also when i look at the code for a print it has Y coordinates less than 315 which isnt on my build plate.

@alankilian
Okay ill do that and let you know how it goes. Since I had to change my home all coordinates for the Y position when the Z axis is homing, will this effect coordinates for a print?

@alankilian Everything was homing fine in open loop so I switched to closed loop on the X and Y. Using the web controllers movement controls i began moving the x in small increments of 1mm each way and it moved fine so I tried 10mm and it continued moving fine. I then tried homing X and it also homed without any issue. I did the same for the Y and everything worked fine. I then homed all and it did without any issues.

It will not let me post my config file but at the start of a print it crashes into the side of the frame of the printer.

I currently got new closed looped stepper drivers and got the printer homing correctly while the drivers are set to open loop. What is the next step to start tuning the drivers to begin printing with them? Ill post my confige file below.

@alankilian Sounds good thanks for the help! One more question now that everything is moving in the right direction and homing properly can I set my drivers to closed loop?

@alankilian Will this effect the positioning now when I go and try to print?

@alankilian I noticed that my Y coordinate was reading 315 where it originally was deploying my Bl touch to home the z so I changed the Y coordinate for the first probe point to Y315 instead of Y 75 and the home all worked fine.

@alankilian Im clicking home all on the dwc.

@v-a-m-p-printing-snproj
Is it possible my cordinates got all screwed up? Should i reset all my homing?

@alankilian Oh it was printing before I put the closed loop drivers on. I got it to home the x and y fine separately, but when I home all itll home x and y and shoot off to the corner and trys to keep moving without homing the z.
