Hello,
@Veti i'll get some new thermistor in a few days when i order a few more parts that i need. the heater is already new and 24 V.
I'll put a second linearguidance to the diamondcarriage.
I figured out that during the fast print, it moves to much (0.5mm). the printed corners are not straight.

Yesterday I scripted a wipetower into prusa. My goal was to evitate oosing colors into the actual printed color while toolchanging. That worked also fine but wasted a lot of fillament. Luckily the printed part was perfect.
I worked with the setup that @deckingman mentioned in his blog (toolsetup: 0.9:0.025:0.025:0.025:0.025....) but the inactiv color oosed somtimes into the actual color.
Today i'm going to ad a servo which will whipe the nozzle and catch the filament which is purged. Like this i'm going to avoid this wipetower an ooze out the unused color at a specific height and befor a toolchange. and prepare the actual tool.

Update:
I did the temp towers. As you said, it is recomandet tu use the lowest temperature possible; in my case it was 190°C.

I just have to set now the stalldetection and everything will be working.

Thanks for your help

Update:

I've mesured the resistance of the thermistor an succesfully put it into the config.g .

But I had some trubble. I had no thermometer, but I had another printer who still worked fin. so I put the thermistor into the hotend and configured the tempretures at this printer. Then I was able to mesure the resistance of the thermistor. I did it at 10 °c stepps. I putted the results into an excelsheet and could verify if it was a curve at the diagram i made out of the results.

Like that I got this result at the onlineconfigurator:

• T99074 B6026 C2.830042e-7

I put this into my config and run a few printtest just for fun.

Now I'm going to make the temperature tower that @deckingman suggested

ok. I see; i didn't click on the beta.
thanks alot @Veti and @deckingman
this helped a lot

ok I'll do it tomorow because the printer is still working now an and still hot.
Roomtemperature 21 or 25 °C?

Would it help if i mesure the resistance of the thermisto to gett an approximate value?

Ok. I'll redo an PID tuning, maybee i've made an error during my lest tuning.

The strange oozing behaviour is something i have seen a lot. But during a layer there is no probleme while i made my last printtests. It's just at the beginning.
I've already reset the retraction to 2 mm an it still works fine.There were other issues that made me think that i have to set it higher, but now i know better. (like you said, high retraction caused blockage)
It also made that other filament melted into a layer where they didn't belong.
I'm also concerned about the pressure advance. As i can see on my testcubes, the printer has issues to extrude the same amount of filament after a corner. And i think it slows down the printhead?

• Your proposes:

1.This is a good point, i printed PLA with 215 degrees but as it looks it was a mistake. The PLA i have melts at 190 degree so i put it now at 195.

2. That was also my toughts, so ill tri to make it faster, for now i'm at 75mm/s while printing and the fastest non printing move i tried was 130mm/s.

• Speed:
  This is why i'm asking for the high&low endstops. So it would synchronize and would be more accurate for higher speed.
  If i'm right the stepper can move faster and have more torque due to 24V?

@Veti do you think that the blobs come from a fault temperature mesuring?

No i don't have something like this

Isn't the torque to high for a PLA Holding?

generally you reduce the motor current while doing stall detection
see
https://duet3d.dozuki.com/Wiki/Stall_detection_and_sensorless_homing

Ok. I'll take a look and will give it a try.

@FITT said in First Post & few Questions (Low+High Endstop & Blobs Issue):

No I don't. I also reused them from the old printers.

do you have the marlin value you set?

Do you mean this value?
A26.7 C106.8 D2.4 S1.00 V23.8 B0

@Veti said in

for x and y it does not matter (unless you need restart after power failure)
because if the print is shifted by a fraction of a millimeter on the buildplate it does not matter

Ok.thank you, I'll give it a try.

@Veti said in

do you have the make of the thermistor?

No I don't. I also reused them from the old printers.

I'll look up for the value for the thermisor. I tuned the bedthermistor once, and all the other are the same brand. Do I have to put the special configuration at all thermistors ?

The idea with the shime is good, but I can also take the steppercoupling out for 2 mm and get the same effect.
I dismissed the idea of stalldetection because i thought it could destroy the stepperholding due to much vibrations. Or it would press leadscrew out of the bearing and so it won't be precise enough. I never tried it.
Is stalldetection even precise enough?

Hello Veti,

this are direct driven extruder from an old printer. I took it from 5 old printers where the printbed was srewed (a dobot replica,singma XGM-5a: https://item.jd.com/32249923157.html)
I reused the steppermotors and the extrudermechanism. The other parts are from doltmechatronik.de and reprap.me.
E85.6:85.6:85.6:85.6:85.6 is a weird number, but i callibrated the exdruder like that and it worked fine.

The reason i want to use high and low endstops is, that i want the printer to synchronise during homing not while printing. I can adjust it manualy but that is not my goal. There is a diffrence of 2 mm at the end of one leadscrew and at the beginning of the other.

I also already tried to rewrite the homeall.gcode, but it never triggered the second endstop. Now it just uses one an then stops.

It also works fine, but sometimes it blocks and the movement aren't parallel anymore.

Thanks for the tip of backlach, for now this isn't prior. But I'll change it in the future.

I've tried to put the endstops togeter at the M574 code but it didn't work.
You said that I could change the endstopbehaviour by the fly. So that means, I can put a remap after the first endstop is triggered in the home code?

Here is a picture to explaine my idea:

At low speed it works good but at high it blocks sometimes.

I took out the thermistor setup because the post got over 20000 letters. I'll repost it.
I'll put it now here:

Thank you for your reply

Hello everybody,

this is my first post.(Please excuse my bad english it's not my native language)

I've been printing for 8 years now, but with the first M3D Micro beta printer that came out in 2012, but now it is to small for me (10x10). Now I have built a bigger cartaisan printer on my own.
I have learned a lot out of this forum and found a lot of solutions while reading.But now I'm stuck at a few points.
First of all:
Thanks to @deckingman who inspired me to build a multicolor printer by reading his blog.
Of cours also thanks to @DC42 for his help and solutions in this forum.
I'm really glad to be a member in this community

So here is my setup:

• Cartaisan Printer
• Duet Wifi v1.04 + Duex
• Dual X and Dual Y and Tripple Z axes
• 5 extruders (Magenta, Yellow, Cyan, White, Black)
• 12 stepper motors NEMA 17 (max 1500ma)(10 on Duet+Duex+2 external)
• Diamond Hotend 5 in 1
• 5 Bowden tubes (80cm)
• 30 x 30 cm Printbed
• 7 optical Endstops + BLTouch
• 2x Vin @ 24Volt and 600Watt (1. Duet+Duexan 2. Printbed via Mosfet)
• 2 Fan + 5 Blower (External Driver, Mosfet, 2 Duet+Duex, 2 Diamondcarriage an 1 Partcooler)
• 5 Activ High switches as filamentsensor*
• 5 temperature sensors ( Hotend, Printbed, Duet, Mosfet & External Driver)
• actually there are 17 Tools set
• RRF 3.1.1.

(* It didn't work well, the printer kept restarting at the beginning of a print, so i deactivated them. Too much noise interferences. I will replace them with other sensors)

I think that's it.

I designed this printer by myself on Solidworks, so all parts are custom made an printed with a small printer( a gift,chinese brand: Singma but it had done his job good) Some parts will be reprinted like the Duethousing with this big printer. The one i used just had a printarea of 13x13 cm.

I tried to build a Printer which isn't too big bud also have a big printarea. So i tried to set it as compact as possible. The outer dimensions are 44x44 cm and the printarea is 30x30 cm. The filamentspool are mounted outside on the left handside.

I've already done some prints an a lot of tests. The instructions an the forum helped a lot, so that it wasn't that hard.

Now my issues:

• I got a dual X and dual Y setup, it also works very well. But it just uses one endstop switch. it worked good at the beginning, but as i speed up the speed of the axis i got some issues. The carrier stuck on Y axis and the Printhead didn't move or just a bit in that direction.
  The reason i speed up the speed was that i tought that it will be usefull to evitate blobs at the beginning of a layer. (At the beginning it was lower and worked very good)
  I already set Firmware retraction (8 mm) an pressure advance (0.8) but the blobs never fully disapeared. But it was already better.
  I could set down the speed, but then the blobs will become bigger.
  I think the longer the hotend stays over the beginning of a layer, the worser the blobs get.
  By the way, I use the prusa slicer, it can run 17 tools without crashing.
  Slic3er crashed all the time. I also modified Cura to have 18 tools but it get very slow and i couldn't see every icon on the screen, that's why i'm using PrusaSlicer. There I enabled also Firmware retraction (all 5 filaments are beeing retracted)

• My question is:
  How can I set two endstops at each end of the axis? (High and low)
  Ass you can see on the pictures, my dual Axis setup is mirrored*.
  I want him to go to one end and after i want him to go to the other end.
  I think then it will be fully synchronised and wont stuck anymore.

(*Saved place to keep the printe compact)

• And if I have to set down the speed, how could i evitate these blobs?

Here is my actual configuration (shortened):

M207 S8 F4000 												;set firmware retraction
; Sets filament diameter for all extruders, which also enables volumetric printing
M572 D0:1:2:3:4 S0.8 ;
M200 D1.75  															; set all extruder filament diameters to 1.75mm

And here a few pictures:
( Some of theme are old ones)

Here are some of my prints i've already done for testing; ther you can also see the blobs and the progress of getting rid of them.
In some Picture you can see that one colour didn't extrudet but i fixed it.

yhis ist the best resultate i get.

maybe someone has an solution for my problem

thanks in advance
