This is a two part inquiry.
This weekend I tried calibrating the machine for the first time, following the instructions from the “Actions/Calibrate” menu. I’m uncertain that I did it right but here are the chain measurements.
I forgot to take an image of the 1-5 cut measurements but I can attach that later this evening. (Sorry). I do remember that the distance from cut 1-2 was smaller than cut 3-4.
Inquiry 1): I’m looking for guidance for qualifying the calibration.
@Dustcloud I was reading your posts about your indepth look at calibrating the machine. I’m new to this part of the machine but wasn’t sure if you had time to support a fellow Maslowian.
Inquiry 2): I’m in the process of trying to trial cut sample designs out of foam and have come across the infamous “Keeping Up” error message. First thing I checked were the motors. I used the “Test Motors/Encoders” function and all motors passed test. Second thing I did was fooled around with the “Position Error Limit”. I change the value from 2.0 to 20 and I was able to consistently make a bad parts (See picture below). The sample is supposed to be a square coaster with “WT” engraved in the center.
What I observe is that the machine has a difficult time machining the overall profile of the coaster…and for some other reason the depth of cut across the engraving is slightly shallow on the ‘T’. I’m not overly concerned about depth yet as I’ve been able to make cuts consistently without an issue. I will address depth later if it is still an issue.
I have attached the coaster nc file to this posting for reference.WT Coaster_11-4-18.nc (15.3 KB)
And just for reference this was my first real cut. This cut is what made me realize that the machine needed to be calibrated. The overall profile of this cut is not square, hence the need for calibration.
Thanks for your support.
