Hey all!
Let me start by saying, I’m in no way bashing 1F here, I’m simply looking to see if I could improve machining times on a operation that takes many hours.
After watching some comparo vids on YT it seems that one of 1F’s competitors can achieve much faster cut times as a result of more aggressive (approx 3 times faster) acceleration settings.
I understand that setting the acceleration higher could cause serious issues under less than ideal circumstances but was wondering if at least some improvements could safely be made for specific scenarios?
I’ve modelled and toolpath’d a 3D terrain map that is approx 14" square.
The clearance pass is only about an estimated hour but the finishing pass is 10 hours!
I’m not looking to cut corners on jobs that might take half an hour or so but saving say, 20 percent on a 10 hour job would really be worthwhile.
I’d be looking at perhaps changing acceleration settings for the 3D finishing pass only, and then putting them back to standard immediately afterwards.
Have any of you tried this and if so, what was the outcome?
Cheers

First thing, is it a 3D model or a 2D relief?
If its a 2D relief click on the vectors in node edit mode, if you have hundreds of nodes that will indicate a start and end point of tiny little lines that the machine must treat as individual parts To fix this right click and convert to bezier curves. The curves smooth out all the those little lines into longer ones. That will speed up the carve time tremendously.
Hey Ken,
Thank you very much for the reply.
I’m not 100 pc sure if it’s a relief or 3D model, though I strongly suspect the latter.
It’s an STL downloaded from here:
…and imported via the import Component/3D model dialogue.
I don’t appear able to select or even see any vectors in node edit mode.
Cheers

Ok so 3D models are different but depending on the toopath strategies- clearance tools used, raster cutting etc. You might be able to optimize the time. I generally setup a job save it then play around on a copy to see if changing different tools stepovers etc decreases the time.
The other thing to remember is IPM if you speed up lets say 300IPM the rapid acceleration/deceleration of the stepper motors can result undesirable finishes or chatter marks. You need to ramp the acceleration/deceleration so there isn’t any abrupt start stop motion.
Hey Ken,
Saving multiple files and playing with them is a very good idea thank you!
I actually already do that for the model itself, didn’t think about doing it for toolpaths!!
I presume the accel/decel in conjunction with the actual rapid speed is what is referred to as ‘jerk’ in the BB controller settings.
I believe the Masso only has the ‘acceleration’ parameter.
I will see what I can do with strategies.
I’m still interested in what changes to acceleration may be made though.
I’d like to think the 1F might be able to be pushed a little further…
