so whose gonna be the first to print the default pyramid WITHOUT the step then?
Steve N | Creator of things both virtual and physicalOMG !!! cant wait to get home.. i will print one for u and me =D
It really prints small stuff damn well I tell ya. DAMN WELL. Good job guys! But i am only bothered by the inability to control nozzle heat manually which makes you unable to do manual purge.
I found a bug. If the layer is too small. It doesnt even print lol
I’ve not tried to print anything with the new release yet (our machine is currently in Portishead) but the scale factor still only allows integers, from what i’ve read a scale factor of 101.7% is suitable for ABS.

@jamie Look here: http://www.cel-robox.com/forums/topic/possibility-to-set-a-more-precise-scaling-in-automaker/
Also, I raised the ticket with the same issue yesterday. Beside that - fix is 5 minutes work if that much. At least it was for me (again - check the thread I’ve posted). I can make a patch, but again not sure if that’s the right way forward.

@azk13 some directions on how to preheat the nozzle in the link below. The gcodes to do this for the head and bed are in the user manual towards the end. This should be brought back in the later AM in a sort of advanced mode based on AM tester’s requests.

@clicky @jamie the formula to account for abs shrinkage was further tweaked, from what Pete said even he uses it and Cel is thinking of potentially incorporating it in a later AM release. The lattest we have seen is in the link below.

Moh@mistsoul thanks! i hope the new version with that function comes soon. Typing in the g code is troublesome.
@mistsoul Now, there are two separate issues here:
1. should AM automatically account for ABS shrinkage and how, and
2. should AM allow decimal places in scaling
For 2. I believe it should allow at least one decimal place, and regarding 1… Well - not 100% sure that link you pasted was talking about AM (and Robox in matter of fact) automatically adjusting for ABS. It was more fine tuning accuracy where extruded width/depth/height wasn’t 100% correct (nor 99.99% in that matter).
Correct me if I misunderstand, but AM does not - nor probably will automatically correct for ABS (nor other material) shrinkage. It was thought that it does but proven wrong.
And last bit - you got me with quoting my older post
: I was about to write something similar again (plug rambling should it really be M103 or M104 and I think that there’s no difference if printer is not printing a job) but got distracted (needed to do my work, too O : ) and didn’t. Good as I completely forgot about that post and would be repeating myself.After some testing last night things seem pretty good so far. Cura seems to do a better job at slicing.
I did notice one issue: it seems the normal and fine default profiles use the 0.3mm nozzle for the first layer. I was printing the bigger gear in this model at 75% size, and the first layer kept being ripped off (both with PLA and ABS) using the normal default profile. The extruder moves very quickly when not extruding, and in doing so seems to jerk the newly printed filament off the base. (I tried calibrating the height but it didn’t help so far.)
I solved the problem by creating a profile that printed the first layer with the 0.8mm nozzle. But I wonder if there is a way to make the extruder move slower when not extruding while doing the first layer?
I noticed the default print settings seem to use the 0.8mm nozzle only in draft mode. AFAIK the idea with the bigger nozzle was filling at a greater speed. Are there issues with quality since the larger nozzle is not in use with the normal settings?
@clicky below is the post where Pete said that this may become part of a future firmware update

In my opinion AM should allow decimal places and also account for ABS shrinkage as an advanced option, this should not be something that is automatic as in a preset function. We should be able to go to our options menu and pull down a list of material and have AM adjust the size of the model to account for the amount of shrinkage based on manufacturer’s data and test done by Cel on Robox with ABS and other materials. So this should be something that the user manually selects without having to mess with percentages and decimal places. The user will only mess with those, when this shrinkage adjust setting l fails to work properly, possibly due to different printing environments. I am not saying that this will ever get implemented in Robox as I described it, but it is just a thought and something that could be thrown into the advanced settings that Cel is working on for the next release of AM.
Moh@maxromantschuk we could change the travel speed which was preset to 300 mm/s in the previous version of AM by changing the print profile manually, but in this new version that function no longer exists. I am sure that there must be a way around this issue without having to alter the travel speed, such as making sure that the bed is flat, that the ambient is reached and fine tuning the calibration, as in manually altering some of the calibration so the print works better. Some of the calibration discussion on the Roboxing Wiki below and how to fine tune it still apply to this version. Give it a try and let us know if you notice something else.
