Also, it's evident that the bottom surface is not as compact at the corners as it is in the center. The masking sheet I pasted on the print bed was charred underneath. You might notice slight charring on the bottom right corner. I just want to know what could've caused this problem, whether there are any other possible solutions, and how to get started with Repetier framework.Įdit2: Attached image is the bottom surface of the 100 mm cube. Please let me know how to figure out what to change and by how much.Įdit: I agree this is quite similar to scaling issues thread here: Scaling/size issues in delta printers The printer runs on Repetier 0.92.6 and I've been reading about it but its honestly intimidating to me. The print head stutters and this is causing sharp vertexes in between curves and some little blotching of material. The Z dimensions are perfect though.Īlso, there have been weird 'lags' while printing larger objects. I tested this by printing cubes of 10, 20, 30 and 100 mm. But I realised later that X and Y dimensions were incorrect (larger by 4.6% to be precise). To print again, I compensated for the Z-direction by giving a global offset (2.65 mm) while generating G-code. The sensor needle does come down to touch the bed but it takes a longer time per point since the distance travelled is more now. In practise, the computations can be speeded up using reduced versions of X and Z. When that runs now, the head starts its vertical to-and-fro motion from a point considerably higher than where it used to start from earlier. digits: When non-NULL, output values close to whole numbers will be rounded using digits as input to RoundWhole. It takes three points on the bed where the sensor needle comes down to contact in a vertical to-and-fro motion. The printer has an auto bed levelling function that runs before every print. I know this because when I gave the print again, the nozzle hit the print bed and started grinding. When it rebooted, the Z extents were screwed up. I had to pause an ongoing print (because of complicated reasons) and that caused the printer to reboot (I don't know why).
