Last update on this topic.
It is dialed in now and it is fantastic.
I wont use any other board on any printer from now on.

It's a simple cartesian but wow does it print well.

Thanks to all of you my carthesian is printing now. Currently tuning acceleration and jerk. I also need to center the pritnbed still as you can see.

Making good progress though. If this goes will I might upgrade my delta to a Duet too.

Apparently the thermistor was screwed in too hard. The set screw put too much pressure on the wiring. It works now.
Pid tuning the hotend now. Weeee!
Sure had some hurdles on the way on this one but the DuetWifi really grows on me. I love the webinterface and the fact I can modify the config via interface - that's brilliant.

Thanks. Yep the Thermistor is dead out of the box. Plugged in a different one and it reads room temp.
I got some teething issues on this one.
Thanks.

Thermistor always shows 2000 C.

Closing in to get it running. Axis Home. Endstops work. Fans work. Bed heats.
Only the hotend keeps bugging me.

It's a 3d Freunde e3d Full Metal Hotend.

I get the error: Heater 1 fault (T0) - 2000°C

I tried the original E3D thermistor values. I tried the values that work for the 3D Freunde Hotend in Marlin (B 3950) but all I get is a heater fault.

The thermistor and heater are wired to E0.

Heatbed works fine. Pid tuning it right now.

Thank you. I will try that.
I can't use thos commands. Insufficient axis homed. Only works after homing I guess? I managed to fix it now. All axis homing against endstop fine.

Fixed the fan. I got an issue with z homing. It tries to home on top but I got a min Z endstop.
Considering it lifts z correctly before homing X and Y I think the Z axis direction should be correct.

I've added the z homing file.

I am sorry for all the questions.0_1545818773565_homez.g

@wilriker
Changed steps. Thank you.

Edit: Fantastic. Making progress. All endstops working. Axis are homing.
Now On to the hotend and the no power on fans issue. I shall read up on it first though. I went at this a bit to unprepared.

Thanky ou very much btw. I am starting to get the hang of it.

@wilriker

Thanks a lo. I will look into it. The Endstops were the wrong way round. Fault number one solved as well.
Sorry for my stupid questions. I am new to this. I thought the basic config of RFF config tool will get me somewhere. I found no basic values to start with for the anet.

X stall detection is because one switch died. I just fixed it though - back to endstop.

@veti
Yeah makes sense. But can you see faults in the config.g?
I am far from anything workable. The hotend throws out a fault. The fans have no power (allways on fans as well - 12V fans, 12V PSU).
No endstops. A moving Z axis when tryign to home X or Y. I don't even know where to start really.

I never had trouble with marlin but this leaves me puzzled.

Ok. Z motors run ok now that they are not in series anymore.
Homign does not work at all though. Homing X and Y moves Z axis still.
Homing Z axis runs the axis down into the switch that does not work and it keeps on running intothe switch - the switch actually died broke this.0_1545766351395_config.g

@dc42 homing doesn'
t even get to the endstops. The z motors run uneven. First one than the other with a horrible grinding noise because x axis gets uneven as result. It is not a mechanical issue though.

Just endstop. I found another thread with exactly the same issue tho. His Z also went up and down erratically.
Apparently two z motors in series on a 12v PSU are too much. That guy fixed it by using another stepper for Z 2. I will try this in the evening.

I am a fool. I did not see I can clock on the config values and get new options to choose - this should solve the termstor. I'll keep on working through the wiki and report back.
Thanks a lot.

The X and Y motors move th right way when I give a +10 input or -10.
Z does nothing at all.
About thermistor: Where would I selecte asemitek thermistor in the configurator - I have no such option.
I read through that guide but I thought I get something sort of workable to start with when going through the configurator.

Hello guys.

I just finished building my AM8. It is no Anet A8 anymore. All I took over is the heatbed and the motors.
Extruder is a bondtec and the Board a Duetwifi.

I just ried starting it up after wiring it up according to the guide. It is a dual Z motor Prusa-like cartesian printer.
I wirded the to z motors in series according to the Duet Wifi Connections pic.

When firing up after going through RRF Config tool I have two major issues.

1. I cannot home any axis. I can move X and Y axis with commands just fine but when I home them the Za xis goes a bit up and then a bit down - in a very uncoordinated way. Same when I try to home Z. Basically no matter wich axis I send a home command it does this!
   I expected the axis to run into the limit switch that I configured.

The other issue is that the thermistor shows a fault. I use a E3D V6. I suppose the default values of RRF Config tool are wrong for this thermistor?

Any help would be apreciated. Are there any base configs for similar printers I could learn from?

Thanks in advance for any help.
