Hello everyone,

This is just a quick thank you to the community for all the help people have provided to get my replicator 2 Duet conversion up and running.

I have never built or programmed a printer before but all the resources on the Duet documentation site and the various community threads have made this a real pleasure to attempt.

My first prints have been ran today and im extremely happy so far, i still need to perform some calibration work and tweek some settings for the Hermera hotend but having the printer functioning again is a relief. It feels like loosing a limb not having it there when a job presents its self.

Anyway this is all a great warm up for my next project the XL printer pictured below :-).

Thank you for all the help, i now have all the homing moves going in the correct direction and a 0,0 point set at front left of the bed. The final issue turned out to be the X,Y motor directions, so a quick reverse of the M569 command got it all moving correctly.

Thanks again for the patience in explaining all this.

Dan.

Does this need changes to the m569 command for motor direction? The behavior i now have while testing this on the X axis is the axis will home away from the end stop or if negative values are used in the homex.g will home towards the endstop perform the correct back off and re-trigger operation then wont let me jog the carriage in a negative direction only further in to the endstop.

@infiniteloop

So iv poured over that link for some time and it seems my solution has to be two minus values in the X/Y to account for the trigger position of the end stops then simply define the maximum print area the nozzle can reach.

Yeah the intention is for the end stops to be positioned in the right rear corner of the printer (replicator 2 conversion) if looking at it from the front as in the image below.

From you explanation the tool nozzle is assumed to be the 0,0 point by default and you need to define the difference between this 0,0 and where the endstops trigger?

Hello everyone,

I am wondering if someone can confirm how the tool and z probe offsets should be set up correctly? My X and Y axis are zeroed by the extruder carriage intercepting the X and Y endstops, using that zero point i have input the nozzle coordinate as plus 59 in X and plus 56 in Y. My BLtouch is sitting at plus 102 in X and plus 61 in Y, however my reading of the documentation is my probe coordinate should be set from the tool giving 43 in X and 5 in Y from the tool head.

"1X and Y offsets of the Z probe relative to the print head (i.e. the position when the empty tool is selected) can be specified. This allows you to calculate your probe coordinates based on the geometry of the bed, without having to correct them for Z probe X and Y offset."

Sorry if this seems obvious but my experience with CMM would be to set the datums and zero point and everything is referenced off that.

Cheers,
Dan

droftarts,
Thanks so much for the help, the probe is now deploying and retracting on command.

Hello Everyone,

I have been working to install my Creality BLtouch on to my newly upgraded replicator 2x + Duet 2 Wifi. I have been following a couple of threads and blogs of people who have completed it as well as the official Duet documentation. So far it looks like its wired correctly and powers up, however i am struggling to get it to test deploy.

Would some one mind looking over my config.g for any errors or obvious noob mistakes?
Any and all help would be appreciated.

@stephen6309 Thanks im going to look at the firmware versions now, cheers for the help.

It seems i was missing M584 X0 Y1 Z2 E3 ; set drive mapping. After adding this line in i now have my Tool added to the dashboard.

So i have added the following to then end of the config.g

; Tools
M563 P0 D0 H1 F0 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C
M207 S1.2 F1200 ; set 1.2mm retract distance for G10 command

; Select Tool
T0

This does not seem to have added the tool or heater to the web interface, what else could i be missing?

@stephen6309 Hi Stephen, thank you for the quick reply, where should i be calling out the t0? Im rather new to programming and might need leading to the answer haha.

Hello everyone, i am currently upgrading my venerable replicator 2 to run on a Duet wifi and to utilize an E3D Hermera hot end. I have mostly worked the kinks out and am able to move all the axis and home to their end stops, however i am coming up with problems getting the extruder to show on the web interface.

The extruder setup looks ok but it is not recognized and the heater does not heater does not display on the interface next to my heated bed readout. The heater does function as iv been able to run M303.

I would say i have bastardized someone elses rep 2 config file from thingiverse.

Any help explaing why my heater and extruder dont display would be greatly appreciated.
