Tried ABS last night and this am. Printed about halfway then peeled off the bed. Using the painters tape and 90 to 110 deg bed temps. It is just curling off. I will pull the tape and use the recommended hair spray. ABS in the past has needed an enclosed printer to get any results for me.
Ordered some PETG.
How tall was your part? The highest I have gone is only about 3 inches. I printed my print cooler with ABS and it came out pretty good. I did have a layer shift on one part. I am pretty sure the glass moved.
We are going to try to dial in Harry's Pegasus this afternoon. One thing Idid notice on his is that if you don't clamp the glass right at the four corners there is a visible gap between the heater and the glass. I had to put the clamps right up against the mounting hardware.
I will post later about the progress we have. I have a bunch of new info about my printer to update but I haven't had time to out together a good post with info. I am having a medical procedure done tomorrow will I will be laid up for a day or two so I will have the time to put a good post together with pictures.
