it work thanks a alot

thanks I will try that.

I what to thank everybody for help me first. Love how easy it is to work with.

Now my next question is about bltouch. it probes just fine but it doesnt take the first probe in the middle it is about 3/4 back and over 1/4. how can I get it to probe in the middle.

Thanks

I have and bondtech ddx extruder and it need 0.7 amps just want to make sure
I adjusted it right.
"Due to the fact that the DDX uses a 3:1 gearing ratio and includes a stepper motor that is rated to run at 0.7A, nearly half of the current stock "

M906 X800 Y800 Z800 E700 I30

Also when the print ends it backs the filament all the way out. how can I adjust that?

Thanks

ok now i can make it deploy and retract. but when I home It . it gives me and error of zprobe already triggered.

Got it upgrade and the error is gone. but the bltouch will not deploy.

@Phaedrux thanks hope this is the problem.

@Phaedrux i did use the on line generater
