What do you think about the arms from SeeMeCNC ? I heard good things about the Rostock printer

blt3dp. I changed my fans with the Hemera fans from Filastruder and now when I print my fan speed is at 80%. There is a huge difference between them.

Re: Kossel Delta xxl build project HELP - 4 years ago

The black powder may just be "polishing dust". Check and see if the rod leaves a black stain on a clean light coloured rag that you sprayed with WD40 and wiped the rods with. It won't be much black but will be an obvious streak. Also if you have belt drives on your printer you will find black powder below the pulleys. doug_scott Thank you for your input. I checked everything and what I notic

Re: Kossel Delta xxl build project HELP - 4 years ago

With this setup you are going to lose allot of room from the build plate because of the big fans.

Re: Kossel Delta xxl build project HELP - 4 years ago

Do you know any other design to accommodate the Smart effector but with different arms and magballs ?

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

I changed my rods with the new ones from Filastruder. After 2 months I noticed the magballs on my effector and carriage adapters were getting this black powder . I lube them with synthetic grease. The same reason why I changed them in the first place. I don't know why it is doing the same thing. I checked every screw and nut on this printer. Please advice . I'm using exclusive Prusa Slicer and I

Re: Kossel Delta xxl build project HELP - 4 years ago

This is the first print with the new settings. Retraction Length 4.2 in PrusaSlicer. Config.g Retraction : M207 S4.2 F2300 Z0.00

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

I changed it to G0 Z0.3 F1800

Re: Kossel Delta xxl build project HELP - 4 years ago

On Lift Z I have now 0. I have on Minimum travel after retraction 1. Should I change it to 2 ?

Re: Kossel Delta xxl build project HELP - 4 years ago

This is what I have in Custom G-Code

This is the STL I just changed the Z to 50mm

Re: Kossel Delta xxl build project HELP - 4 years ago

I start this print with 3.5 retraction Length under Filament Settings in PrusaSlicer and S3.5 in M207 in config.g After 25 mm I send the M207 S4 F2300 Z0 to the printer and I changed the temperature to 190c. Maybe is just me but I don't see any difference. I also checked that exposed section of the gear on the side of the Hemera and when it retracts it jumping back

I will change this 2 speeds and print something to see

Thank you Viktor. I will open up the gear box and check for any play and report back

Re: Kossel Delta xxl build project HELP - 4 years ago

My Hemera is doing a click when is retracting. I checked the gears alignment and everything is good. I released the tensioner all the way then I tight it up again and I still have that click. I don't know if is normal to do that.

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

I start a print with 205c first layer then I drop the temperature to 195, 190c. The speed I think is 40mm

Re: Kossel Delta xxl build project HELP - 4 years ago

My Bowden tube is 660mm and I use 4.6 retraction and I'm getting a horrible stringing. I will try retraction on the fly and hopefully I can adjust it.

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

In order to use the retraction on the fly from 3.5 to 4.2 I have to send M207 S4.2 F2400 Z0.00 ? I never used the M207 command. Thank you

Re: Kossel Delta xxl build project HELP - 4 years ago

This is the test stretched taller to 30mm. The walls thickness is still 0.5mm

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

I did all the modification you suggested in Prusa and the cube 0.4mm it's looking good now. The walls are still 0.5mm thick. I do have the M207 command in my config.g

Re: Kossel Delta xxl build project HELP - 4 years ago

This is the Thin Wall test cube- 0.4mm sliced with Prusa Slicer. The wall thickness is 0.5. please see the attached pictures.

Re: Kossel Delta xxl build project HELP - 4 years ago

Thank you. Hopefully I finish today and print something tonight. I'm so curious about Hemera.

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

I'm about to turn on the printer and start using the Hemera. What Retraction Length you are using ?

Re: Kossel Delta xxl build project HELP - 4 years ago

Thank you David. My concern is that buzzing/whistle sound from the motor when is not extruding.

by alex773 - Delta Machines

Re: Kossel Delta xxl build project HELP - 4 years ago

This is how I connected the cable to the Duet. It is not vibrating anymore but I still have that whistle noise. This is my M906 now : M906 X1000.00 Y1000.00 Z1000.00 E1100.00 I35 ; Set motor currents (mA) and motor idle factor in per cent

Re: Kossel Delta xxl build project HELP - 4 years ago

I did multimeter it out and I have red and blue , first 2 pins and green and black the other 2 pins connected to each other.This is what I have in Config.g for M906: M906 X1000.00 Y1000.00 Z1000.00 E500.00 I35 ; Set motor currents (mA) and motor idle factor in per cent Should I change E500 to E1100 and try again ?
