Printing scale errors
Posted: Sat Mar 12, 2022 11:56 pm
I am using Greta Stella to print nets on paper to be transferred to other media. I am scaling the net to a specified edge length and printing edge and angle details on the net one facelet at a time. This is all good but for the size of one printed net. On one printer (A4) the edge length is exact to the specified length as far as I can measure it, on the second printer (A3) the hardcopy is about 1.6% too big. That might not seem like much but if there is confusion between the actual size of the net and the dimension printed on it will be enough to prevent the model from assembling properly.
I could re-scale each time I use the A3 printer but then if the actual size is correct the printed dimension will be too small. Also if I want to print larger facelets on the A3 and smaller ones on the A4 and forget to re-scale it will be a mess.
1) Why is this happening?
2) Is there any way I can re-calibrate the erroneous printer?
3) If I cannot fix the printer is there any way to re-calibrate Stella so the printed dimension and physical size of the printed net on a specifies printer agree?
