Re: Be careful when removing the bed - 9 years ago

I brought a new one the other day, so that I could have two beds, one for swapping in so that printing can continue whilst the first print is cooling. Unfortunately this is the new one that has broken, after only the second time I used it.

Be careful when removing the bed - 9 years ago

Just head heads up to be careful when removing the bed - doing it more than a few times is liable to make the bed ends crack off, even if you push down to make sure the silver balls will clear the silver posts that they rest against. I think I am going to add a bit more material to the ends before laser cutting some new ones.

Re: 15mm Calibration Cube - not quite "cube-uler" - 9 years ago

Thanks for everyones suggestions, I bought a new buildtak on amazon, glad I did, as peeling off the old one broke it. I also bent the arms a bit more, and affixed them with cable ties rather than the bolts. The X axis is looking much better, and the cube is coming out with square faces but slightly oversized at ~15.27mm, which I guess could be down to slicing or extruder steps/mm or filament dia

Re: 15mm Calibration Cube - not quite "cube-uler" - 9 years ago

Thanks for all the suggestions and help. I have gone through and checked the tightening and alignment/straightness on everything and now get slightly more sensible values. Diagonal 160.00, delta radius 82.05, homed height 181.82, bed radius 75.0, X 2.39°, Y 2.21° The bed is definitely slightly higher in the middle vs the edges by about 0.2 Z steps, what is the best way to correct for this? sho

Re: 15mm Calibration Cube - not quite "cube-uler" - 9 years ago

Quotedc42 What layer height are you using? The Z height will be rounded by the slicer to a multiple of your layer height. You can look at the Layers preview in slic3r 1.2.9 to see whether it really is trying to print exactly 50mm high. The extra 0.92mm size in the Y direction looks odd to me. One possible explanation is that the probe trigger height varies with position on the bed, and you haven

15mm Calibration Cube - not quite "cube-uler" - 9 years ago

Last night I decided upgrade to the 1.09d-dc42 firmware and the latest 040815 software so that I could play around with the 7 point calibration. I changed the final G30 command from S7 to S6 so as not to change the diagnoal rod length, and after the a few iterations the values settled down and I updated config.g Next up I printed out a 15mm cube, and measured it with a sheet of glass, an enginee

Re: Build your own 3d printer class - 9 years ago

I think that a course is a really good idea. Spreading it over two days would be advantageous, judging by how much we covered in a long afternoon on an introduction to laser cutting course I recently went on. Something on the basics of slicing up your own files to print would be good at the end of the course, which could then lead to other courses. I would include the cost of the printer in the

Re: Fisher SD image 210715 - 9 years ago

Thank you for the file, and all that useful info your reply. I shall give some 6 factor calibration cycles ago until M665 and M666 settle down and then try out the suggested calibration prints. Kind regards Jeffrey

Hi Has anyone got a copy of bed7.g I could look at? as PRZ said, it has been removed from the latest Fisher image. cheers
