Prusa Slic3r config for TierTime Cetus mkII

thingiverse

TierTime Cetus is a very capable printer. Their UpStudio supports printing gcode generated by other slicers. TierTime has officially published only Simplify3d profile, but not for others like Cura or Slic3r. Slic3r Prusa edition has very nice support for 3d infills, and surface finishes, and has good open source community support. I took official S3d profile, and modified it for Slic3r. Several beeps are added as well to indicate when the gcode is transimitted to printer, when the heater has reached the temperature, when the print is done, and finally when the setup is turned off. It also turns off steppers at the end of printing. #### Custom Printer setup 1. Use the instructions given by [myfordboy](https://youtu.be/qoP1aQJikSU?list=LLTHIOT_2-iF8bQOpRRppfuQ&t=473) and level the axis as far as possible. 2. Use the UpStudio calibration screens to calibrate z-axis. If step#1 is correctly done you should get all 0 for each of the 9 points. Note down the z-height. 3. Import the Cetus configuration (in Slic3r File->Load Config, select the ini file in this thing) 4. Edit start.gcode replace 182.9 with the value noted in #2. Don't deduct the 0.5 mm that is required to do in Up Studio 5. In Slic3r create a custom printer profile and paste start and end gcodes from the respective files 6. In the Filament section update Extrusion Multiplier to 23. This basically messes up the filament usage prediction in Slic3r, and I haven't find a way to fix it. Make sure the Z-axis friction holder (small white ring at bottom) is tight. After the print stepper motors are switched off, so Z axis can drop and may destroy to your print!! Every time before you want to print initilaize your 3D printer again using the physical switch since Stepper motors are swiched off, therfore may not in the right position. #### Selective fan usage Cetus turns on the noisy fan as soon as powered ON. The extruder has a pin which can be used for the other accessories (laser was proposed in their [kick starter](https://www.kickstarter.com/projects/854865943/cetus3d-at-199-get-all-you-need-to-start-3d-printi/posts/1695215) ) If you want to use the fan selectively open the extruder cover and llug the FAN wire connector into the LASER contol connetor (the same white connector next to the fan connector) Slic3r gcode already handles enabling and disabling this end point as required (using M42 P15). If you change the fan wiring, then remember that UP Studio doesn't switch ON and OFF the cooling fan! So you would need to remember to print `TurnOnFan.gcode` before issuing normal print command from UpStudio. Later 'TurnOffFan.gcode` can be used to turn off the fan and steppers. If you get an error stating "Failed ato activate the printer" its a known bug in UpStudio and I have raised a request with them to get that fixed. Click on OK and print will go forward.
