Printed bolt threads are wrong direction CoreXY
-
Hello,
I just realized what threads on bolts are printed opposite direction. I have custom made CoreXY.
Can somebody point me out there to look? Slicer settings or I messed up something with wiring?
Thank you a lot!.gcode

i assume that you mean your movement directions are wrong.
have a look at
https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_Testing_motor_movement -
Hi Veti,
No, everything moves as expected, it prints very well. But if I print a bolt - than to screw the nut on it I need to rotate it counterclockwise - should be clockwise.
I already print the same bolt-on my Makergear M2 printer and its prints as it should - tightens the nut in a clockwise rotation.I tried that link and did a test - it does move correct, but it doesn't resolve and issue.
-
if you print something with text on it, is that correct, or mirrored? A quick test item would be Maker's Muse's Ghosting Test.

-
Assuming everything else you've printed to date is in the correct orientation and not mirrored. I'd say you have the model mirrored in the slicer. Does the preview in the slicer look correct? If not, flip along either x or y, not both.
-
Indeed its prints mirrored and also in slicer its mirrored...
I am completely lost there to look
-
go to the menu Mesh -> Mesh Mirror and change the settings there
-
Indeed that helps, but a bit dirty!
It looks i have left hand coordinate system. Is it possible to set it somehow so its prints properly, or i need to switch to right handed coordinate system somehow?Industrial 3D printing service in the Netherlands - gagatstudio.com

If you follow that original link from Veti you should be able to get a right handed system going. You may also need to change your homing files or endstop configuration. Things have gotten a bit muddled.
This may help https://drmrehorst.blogspot.com/2017/08/setting-up-3d-printers-origin.html

I don't know why, but every profile I've ever seen of S3D needed to have "Flip build table" checked for Y axis.
As you can see, the Y axis is positive towards the front from th eback.
Check the Flip build table Y axis and see if it's correct.

I am completely lost on it...
Can somebody have a look, please? Now If I do home all everything goes in the right direction. but then X hits a switch it doesn't go back anymore 3mm to make a soft home. And X-axis doesn`t move after home. If I switch M574 X1 S0 to M574 X1 S1 than X-axis not even trying to move at all for homing. Can somebody guide me through the right process? I checked all links from the wiki, but now it seems I am just more confused as I have no idea if I needed to switch motors wiring or not? Even tho at really beginning I did movement test and everything works well but was printing mirrored anyway.

Can you post a photo of your printer from the front and indicate where the endstops are located?

Hi @Phaedrux
There is it, with X and Y switches visible

It looks to me like you have the homing switches in the right rear corner of the machine, and the motors at the front of the machine. The A motor is on the left (plugged into the X diver on the Duet board) and the B motor is on the right (plugged into the Y driver on the Duet board), the same way I set up my printer (except that I put the X switch on the printer's frame instead of on the extruder carriage). I have the origin set to the center of the bed. Here is the relevant section of my config.g file:
; Drives M569 P0 S1 ; motor A goes forwards M569 P1 S0 ; motor B goes backwards M569 P2 S1 ; Z motor goes forwards M569 P3 S1 ; extruder motor goes forwards M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation M92 X160 Y160 Z800 E411 ; Set steps per mm M906 X1600 Y1600 Z1120 E500 I30 ; Set motor currents (mA) and motor idle factor in per cent M84 S30 ; Set idle timeout M205 X20 Y20 Z2 E50 ; Set maximum instantaneous speed changes (mm/sec) M203 X18000 Y18000 Z900 E3000 ; Set maximum speeds (mm/min) M201 X3000 Y3000 Z1000 E3000 ; Set maximum accelerations (mm/s^2) M204 P3000 T3000 ; Set print and travel acclerations (mm/s^2) ; Axis Limits M208 X-153:153 Y-178:150 Z0:687 ; Set axis minima:maxima ; Endstops M574 X2 Y2 Z1 S1 ; Set active high endstopsWhen homing, the extruder carriage should move toward the switches, regardless of their positions relative to minimum or maximum ends of the axes. M574 statement tells the machine that when the switches are activated, they are at Xmax and Ymax. The M208 statement tells the firmware what the ordinate values are at those positions.

Sorry, I got distracted by baby. Here's the post I started earlier in case @mrehorstdmd post didn't get you sorted.
Ok, so -X moves to the left, +X moves to the right, +Y moves to the back, -Y moves to the front. 0,0 is at the front left and 200,200 (for example) is back right.
You have the x endstop on the low end of travel (looks like its on the left side of the extruder carriage and the trigger bolt on the left side) and the Y endstop at the high end of travel at the back. The endstops look like makerbot style switches with an activation LED on the PCB, so active low.
M574 X1 S0
M574 Y2 S0Then in your homex you need to change from moving to X positive to X negative, like so:
; homex.g ; called to home the X axis G91 ; relative positioning M913 X50 ; set X motors to 50% of their normal current for homing G1 S1 X-321 F1000 ; move quickly to X axis endstop and stop there (first pass) G1 X3 F1000 ; go back a few mm G1 S1 X-321 F200 ; move slowly to X axis endstop once more (second pass) M913 X100 ; set X motors to 100% of their normal currentHome Y looks correct.
Homeall looks correct as well.
If the head isn't moving in the direction you expect (like -X going to the right) then one of the motors is either plugged into the wrong motor port, or needs to be reversed. Note your motor connections as described by mrehorst, and use the motor direction test from the corexy setup link to verify that the motors are turning in the right direction.

Damn! Thank you guys a million!
That was making me nuts... Eventually, I needed to swap motors indeed and reverse them:M569 P0 S1 ; physical drive 0 goes forwards M569 P1 S1 ; physical drive 1 goes forwards@Phaedrux thanks a lot for a sketch and tweaking the homex.g - that solved it all.
Minus one issue - million to go :))

@felt342 Good! Now you can get to the fun stuff like calibrating the extruder...
It isn't entirely necessary to have the X endstop on the X axis. Doing so requires an extra wire or two going to the extruder carriage. I prefer to minimize wires going to the extruder carriage. You can put the X axis endstop on the printer's frame instead, in which case you'll have to home Y before homing X. I've been doing that in my printer for over a year and it works fine. I just modified the homex.g file to home Y before it homes X.Older version of extruder carriage with X endstop mounted on printer frame:

It is a good point, I am thinking about to stick it to the frame. May I ask you that tunnel switch, is there any advantage compared to normal switch?
