one other thing why dose the ip dress change every day is there a way to make it fixed ?

figured as much was confused that cura spat out 1.2mm but i then realised i entered it into the wrong config tab… felt by hand yesterday pinching with fingers and couldn't really stop it

and basically after consistency more than anything hot maybe 30 deg..

Below are pictures of the first layers am i over extruding ? also what hight do you guys recomend from the bed with a 1.2mm nozzle ?

First layer hight (Pictured )coming out at 1.2mm

Good news guys its all working fine now noticed small break in the wire on the cheap motor thanks to tony for that ! also found that i needed to change the 100:100 on the mix ratio to 1:1 for correct proportions i.e. it extruded a meter instead of say 10mm printed 100x that or something along that line but all seams well

and as for the brittle filament i will cross that bridge if it proves an issue thanks for the heads up i made sure the bend radius was not crazy for the hole run

its not so much heating the chamber just keeping it consistent as you can see the printer is in a small mill without heating I'm sure the idea with 1x to 2x helper extruders is sound its just this odd behaviour from the furthest will it be due to length or something like that ?

Reason for the current arrangement is for a heated chamber i.e. the hole thing will eventually be enclosed

strange might be so you need to be logged in to a google account

excuse the untidy wires etc still plenty of messing about before tidy up

How do you upload pictures on here not used to this forum format ?

Done the continuity test and all 4 wires test fine and no weird resistance between coils so I'm kinda stumped when i get home i will upload picture of the gantry

Ok tony i will do a continuity test tonight for all wires

Also notice that when they are both connected the one with the trouble just buzzes and the other one is unaffected

If someone could send a picture of the duet with the drives numbered from above say what the stock z is numerically

Small update when i use the smaller length wired motor on the same drive output it behaves as normal

could this issue be the wire ? because i have small gauge wire to thicker then thiner stepper wire again ?

Right guys I'm just getting the motor to rotate but i get buzzing sound and when i put a bit of force against it rotating it skips back and forth in direction until it recovers and continues in correct direction tried turning up the amps

The issue i was having is I'm using cable chain with a fairly tight bend radius so we needed assistance across the length due to slippage and the issue with using the larger diameter tube is fitment within our chain although we may heed the advice and give it a try if the new solution fails to work please bare in mind the main reason for having an extruder closer to the hot end is for flexible filament while using the kraken so no room for direct extruder above the hotends unfortunately.

dirt and debris should not be an issue in the tube due to a two stage filament wipe

i will update when I'm with the printer thanks guys for the feedback/advice all duly noted

Chris

Thanks DC42 so in my example above i should add in the Config.g

M568 P0 S1

M567 P0 E0.0:0.2:100:100

? and where will this need to be placed in the config near the top or near the extruder config section again thanks

Using two extruders on a long Bowden tube one assisting the other…

Basically we have a large printer with a very long Bowden tube about 5mt i have been using a single driver the one that would normally be for dual z axis motors with good success but of course after a few minutes printing the extruders would slip (2x E3D Titans) each 2 meters roughly apart wired in series on the dual output for the z axis just mapped as an extruder instead. The solution i had was to shorten the tube and extend the wires for reference we are using shielded igus 4 core but then the motors started acting rather strange they would intermittently work or stall or you could change direction with manually counterrotating the motor mid process my thoughts were this was due to the higher resistance and differential currents for the motors as they were effectively further awn in terms of wire length so i tried turning up the feed power to no avail. so i then wired them up as separate drives i.e. each motor has a mapped drive for the same tool or hot end 2 or 3 extruders for one hot end... but an error popped up when i was on the print screen that looks as follows

---

! M120
M83
G1 E-10 F2400
M121

Wrong number of extruder drives for the selected tool: G1 E-10 F2400

---

But when i checked on the tool library in the online menus the controls reflect 2x active drives and the hot end heats up and shows correct temps etc so I'm stumped

i followed the guideline in the documentation

M563 P0 D0:2: H1 ; create a tool using extruder drives 0, 2 and heater 1

Please can someone let me know whats going on ?
