@v-a-m-p-printing-snproj said in Connecting stepper motor encoders to closed loop drivers:

I changed the direction with the switch on the driver and it printed alright, prints were sloppy. I ordered a new hot end so hopefully that helps with the sloppy prints when i get it moving right again.

OK, it's good to hear you've got it running.

Let us know when you have a new hot-end and have some new results.

[V.A.M.P printing snproj]

@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.

[V.A.M.P printing snproj]

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

[alankilian]

@v-a-m-p-printing-snproj

Can you describe what you are doing to accomplish this?

Are you clicking the "home all" button on the DWC or are you running the homex.g file by hand?

[V.A.M.P printing snproj]

@alankilian Im clicking home all on the dwc.

OK, this is your homeall.g file:

G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-420 Y420 F1800 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X-420 ; home X axis
G1 H1 Y420 ; home Y axis
G1 X-5 Y-5 F6000 ; go back a few mm
G1 H1 X-420 F360 ; move slowly to X axis endstop once more (second pass)
G1 H1 Y420 ; then move slowly to Y axis endstop
G90 ; absolute positioning
G1 X10 Y75 F6000 ; go to first bed probe point and home Z
G30 ; home Z by probing the bed

Type those lines in one-at-a-time in the console while taking a video and we'll be able to see where the error occurs.

@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]

@v-a-m-p-printing-snproj Excellent!

[V.A.M.P printing snproj]

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

[alankilian]

@v-a-m-p-printing-snproj

Now that you've got the closed-loop drivers connected, please start a new thread completely describing the problem you are having and people will take a look and respond.

Posting all your config and homing files in that new thread will help people help you.

You should mark this thread solved.

[V.A.M.P printing snproj]

@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]

@v-a-m-p-printing-snproj

Start a thread about "Closed-Loop tuning on CL57T stepper driver" and we'll talk there.

It's going to be a long conversation I bet.
