Configuring Ultimaker

PS - you could use the config tool at reprapfirmware.org to generate your config.g and homing files.

Well im slowly getting there. I've used the config tool at reprapfirmware.org but im still not sure how the marlin configuration applies to duet configuration, especially the minimum speed, the acceleration and the current settings.
I now can move the x-axis pretty much smoothly at +/- 10 (even it starts to make a noise after some traveling and it slows down). The behavior on the y-axis is similar but a bit more worse than x. At +/- 100 the behavior gets even more worse.
Still no luck with the z-axis.I keep trying, i know i will get there some time.
Here is my current config.g:

It looks to me that you have copied most of the settings correctly from that Marlin config file into the config tool, assuming you have made the correct choice of the HBK or not and GT2 or not variant. You appear to have assumed HBK but not GT2.
RRF doesn't have minimum speeds, so nothing to do there. Your accelerations look OK to me.
Regarding motor currents, do the motors have part number labels on them? If so then I suggest you look them up to find the rated current. Then set the currents to between 50% and 85% of the rated current.
Does the machine have 1 Z motor or 2? If just 1, dou you have the two jumpers in the ZB connector?
-
I have the following motors: SY42STH33-1334A and their rated current is 1.33A, configured I have 0.75A.
Could it be that there is an issue with the connection of the motors? I have one Z-motor and there were already jumbers in the ZB connector. The only thing was, that the pins were bent backwards in ZA connector from the shippment. And Yes, i have a Heated Bed on my UMO, but it is self made and not that one from UMO+.
Furthermore, i still have MXL and not GT2.I'have changed some things in the config, but i still have the motor issues on the X and Y axis. Funny is, that when Y is almost at 0 then X +/- 100 runs almost smoothely. With the current config i can hear the Z-axis motor starting to work but it seems to me that it has not enough power to lift the Bed.
Note, with the current config Homing works for X and Y.[[language]] ; Configuration file for Duet WiFi ; executed by the firmware on start-up ; ; generated by RepRapFirmware Configuration Tool on Thu Nov 17 2016 21:40:07 GMT+0100 (W.

If X runs smoothly at some Y settings but not others, that suggests a mechanical issue. With power off, how smoothly does the mechanism move, if you move the head around slowly by hand?
Your 750mA current is rather low and on the Duet WiFi it gets rounded down to 700mA. Try 1000mA.
Do you definitely have the correct Z steps/mm? The HBK and non HBK versions have different Z steps/mm in the Marlin config file.

Ok it's getting better:
The x-axis moves all fine now, the y-xis, having the same config, moves almost fine (it only has some issues in one direction: front to back, when moving at +100 it gets stuttering near the end. The other way around works just fine.Still no luck with Z, i've wrongly used 200.0 for the steps but since it is not HBK it should be at 533.3333. So i roundet it to 535. But i'm still not abele to move the bed at all.

Awesome, the Z-axis is working fine now. So only the slight issue in the Y -axis persists, as described before. I'm going to move now to the extrudes and the temperature sensore.

For the Y axis, if you haven't already, make sure to lubricate the copper bushings (utlimaker style iirc). Also make sure there isn't some mechanical interference - stuttering is usually the stepper skipping, which means the stepper is trying to move but can not move the part. It looks like your steps/mm is correct for the system you're on (well, close to 80 or so). Potentially, you could try moving to 32x microstepping and doubling the steps/mm - This will cause you to lose a bit of holding force - meaning the axis will stop easier if there is indeed something causing a mechanical stop and help you pinpoint where that could be. Alternatively, your steps/mm is off for Y (shouldn't be - should be same as X) and if you really wanted to, you could take out a caliper/micrometer and do the following process:
Have the duetwifi move the Y axis 10mm
measure how far it really went
measured/10mm = newssteps/oldsteps is the formula you would use, and solve for newsteps … newsteps = oldsteps*(measured/10mm) -
I really don't recommend using the calliper method to set steps/mm for any axis other than an extruder. You can use them to diagnose if the steps/mm are set wrong (possibly, depends on how wrong) but to set them the reliable method is to calculate them based on the stepper motor microsteps/rotation, and any gearing you get from belts/pulleys or leadscrews.

Sorry to revive a dead thread but did you get it all working nicely in the end @CoolM8. I am nearing the end of my build and am readying myself to start the firmware side of it.
