Craftbot Pro slicer is Printing slower and supports not visible
Quote from Gerald Rodriguez on 2021-11-09, 06:30Hello everyone. I am trying to migrate over to the new Craftbot Pro slicer and have two questions.
- How can I run my prints faster? The material I use is not in the profile list so I used a similar and changed the temperature for my needs but it runs slower. For example the same model in the old slicer would take 8 hours to print is now 12 hours in the new slicer.
- When you press the slice button the supports disappear? They are there you just can't see them. When you print they are there.
My material is PC-PBT from Push Plastics. It is a polycarbonate blend so the profile I'm using is "Prusament PC Blend thistle" I only changed the temperature to work for my Material.
I also get a warning message (attached) that I don't know what it means.

- As I see you use the easy strategy. There you can find a slider labeled "speed" you can increase the overall speed there. With the "default" strategy you will have more control over the specific feed rates all over the slicing process. Your filament settings affect the speed as well, it used to determine the base feed rate as well.
The layer height is a very important factor for the printing speed. You can set the adaptive layer thickness range too
The Craftware Pro uses a more sophisticated way to calculate the printing times. The legacy Craftware calculates the theoretical time only from the given commands. The new CraftWare Pro simulates the print process and takes the accelerations, turns, jerks, and many more effects into account - it is mode accurate but everytime is higher compared to the old CraftWare.- You see the "Top Layer Only" gcode display mode. Have you turned on it manually by any chance? By default it should be turned off. Can you confirm if it was the initial state of the display or not? The "Top Layer Only" does not show the support object models (horizontally striped objects in the Manufacturing page), only the prepared model. However if you use the layer selector slider (right vertical slider), you can confirm the existence of the support gcode layers. If you turn off the "Top Layer Only", you can see the whole gcode with the support extrusions as well - I suggest that.
The warning message:
CraftWare utilizes Permesh Slice aka. Asynchronous Adaptive Layer Sequences. Every (support) object can have it's own adaptive layer thickness calculation. So every support can have independently thick layers on the body part and thin layers near the object, at the support interface.
For example:
'A' support object has 30 mm height, with 300um layer thickness in the first 28mm and 100um layer thickness at the top 2 mm.
'B' support object has 50 mm height, with 300um layer thickness in the first 48mm and 100um layer thickness at the top 2 mm.
'C' support object has sloped interface and 40 mm height, with 300um layer thickness in the first 10mm and 100um layer thickness at the sloped touching part for 30 mm.
and so on.
However if there are many objects, these calculations can be very demanding. So if many support objects are generated, the software suggests turning this feature off to avoid the long slicing times. This way all the support objects will have a common layer sequence (still independent from the main objects).Applied to the previous example:
'A', 'B', 'C' object will be printed with the same layer thicknesses.
0-10mm: 300um
10-40mm:100um (requirement from the object 'C')
40-48mm: 300um
48-50mm: 100um (requirement from the object 'B')
In the end: The A-B objects bottom part (10-40 mm) will have unnecessary low layer thicknesses, and high on details. This will increase the printing time.Best Regards,
András
