Creatbot DX03 - Nightram Settings

Wed Nov 18, 2015 4:39 am

Prelude:
The creatbot can be a fantastic printer, however it is let down by the profiles. It has a maximum resolution of 0.04mm however the simplify profiles only go to 0.1mm. The following information will help others get the best from the printer and hopefully help me improve mine. For $250 AUD, I would expect snappier response from S3D support :(


The problems - inherent machine and the easy fix
Lets face it the printer is a Ultimaker clone. Now we can admit that lets treat it like one and fix it. I will copy the thread I made in 3D hubs and expand here.
Original thread on 3D Hubs

As before, these steps need to be done ASAP or you are just wasting your time. Like the two weeks I have just wasted before writing this. I want to thank Mark Langlais who quite literally lives on the other side of the world to me, and who helped me get mine printing effectivly.

Here are the defaults and the rough fix numbers

Nightrams defaults (aka what it should be from factory):
  • Extruder 607.13 s/mm (factory is 650 s/mm)
  • X/Y leave as is (can be tweeked if required, mine was only 0.3mm out over 100mm)
  • Z 808.00 s/mm (factory is 800)
  • X Acceleration MAX 1000mm/s (factory is 9000mm/s)
  • Y Acceleration MAX 1000mm/s (factory is 9000mm/s)
  • Acceleration 800
  • Maximum X/Y Jerk 10.00 mm/s
  • Maximum Z Jerk 20.00 mm/s

Before you fix the S3D Profiles you need to do the basic Rep-Rap tune as detailed below (or use above defaults)

Basic Extrusion calibrate and so forth
Start at the extruder then work your way around. I disconnected the hose at the top of the bowden, fed in some filament and chopped it off exactly 120mm from the bottom of extruder. Becasue lets face it you wont re-use it (or you will as slurry). Use the controls and feed 100mm of filament through, measure the distance remaining. It should be 20mm, if not its maths time!

The formula is (expected extrusion / actual extrusion) * current setting = new setting
In my case (and more than likely yours) I got (100/107.06)*650= New value of 607.13

Put the setting in and do another filament draw. I bet your bottom dollar it is better. Keep this process in mind and you are armed with the knowledge to calibrate X/Y/Z, although I found X and Y to be close enough.

Here is a video of the process (not mine)Youtube clip


How do I stop the acceleration greater than a jet plane?
Someone in the company thought it would be a good idea to have the accelerations maxed out, Quite literally faster than a supersonic jet plane. To fix this you need a program called matter control. It is one of the few programs that can adjust the firmware in the printer without destroying it.

Put the settings in as such:

Lastly, the plug. What software to use?
You probably have realised it by now that the Creatware is just a sucky version of Cura.even then it is second best to Simplify3D. You have saved a few pennies on the printer so I urge you to buy the software. Here is a basic FFF file for the Creatbot DX03. With the settings within I have been able to reliably get down to 0.04mm successfully. Just lower the speed to 1800mm/m.
Nightrams FFF file


Software tweeks
I like the start and end code in Creatware, so here is my modified version for you to add.

Start code:
G28 X0 Y0 ;move X/Y to min endstops
G28 Z0 ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero extruder value
G1 E15 F200 ;extrude 15mm of feed stock to pre prime
G92 E0 ;zero extruder value
G1 F4200 ;Put printing message on LCD screen
M117 Printing...

End code:
G28 X0 Y0 ; home X-axis
G92 E0
G1 E10 F200
G1 E-150 F1000 ;withdraw 15mm of feed stock
G1 Z280 F3000 ; Lower bed to base
M104 S0 T0 ; turn off extruder T0
M104 S0 T1 ; turn off extruder T1
M104 S0 T2 ; turn off extruder T2
M140 S0 ; turn off bed
M84 X Y E ;steppers off
M117 Print finished.


Hardware fixes
This area is not as large but should be noted. Some things can be software compensated for and others not so.
  • Hot end tube - The Tube inside the hotend on the 3mm is 3.98mm in diameter. This means that there is an excess build up of pressure resulting in webs everywhere.

Hello,
A question!

I want to change te settings:

Extruder 607.13 s/mm (factory is 650 s/mm)
X/Y leave as is (can be tweeked if required, mine was only 0.3mm out over 100mm)
Z 808.00 s/mm (factory is 800)
X Acceleration MAX 1000mm/s (factory is 9000mm/s)
Y Acceleration MAX 1000mm/s (factory is 9000mm/s)
Acceleration 800
Maximum X/Y Jerk 10.00 mm/s
Maximum Z Jerk 20.00 mm/s

But I dont't know how to do it.
I can change te Extruder to 607.1 s/mm in the setting -> motion on my Creatbot DX 3.0 triple extruder.
But don't know how to change the rest.
Would love it if someone could help me...

You have to edit the EEPROM settings. You can do it by manually sending commands in the Machine Control Panel. This lists what commands to use: http://reprap.org/wiki/G-code

For example

M204 - Set default acceleration: S for print moves, R for retract moves, T for travel moves (M204 S3000 T7000) units in mm/sec^2

Any chance anyone has figured out how to disable the auto-shutoff "feature"? I can't express how frustrating it is to start a print with octoprint and have shut off because the screen has not been touched in 5 minutes.

Thanks in advance,

Chris
