I’m thinking my initial bed height might be a tiny bit too high
Hard to tell from the lone picture but your bed adhesion looks fine and then you have serious under extrusion.
No, there’s seriously much more going on than simply underextrusion here. Double-check all your calculated X/Y/Z/E steps-per-mm, arm lengths, etc.
Do NOT do the calculation of filament length (E-steps) while extruding with the hot end. It will give you an incorrect result. Either do it mathematically (preferred) or do it with the bowden tube removed and into free-air.
Additionally, double check your slicer settings too. Slic3r used to have a really painful UI that if you were mouse-wheeling through things and hovered over another UI element, it would increase/decrease that element.
Make sure you’re not printing at 1mm layer heights or something weird like that.
@ThantiK can you tell a little bit more about mathematically method please
@Benjamin_Lukman https://www.prusaprinters.org/calculator/ is a good place to get started. – You’d take the inner toothed diameter of the drive gear, say 11mm – If you’re full-stepping, at 200 steps for a diameter, you’re stepping at 0.055mm per step. This means a it takes 18.181818 (repeating of course) steps per 1mm of extrusion.
Based on your microstepping amount, diameter of the drive wheel, stepper motor step degree, etc - that number is going to change.
Additionally, some people do a trial-and-error. They’ll set their E-steps to something…then adjust the error. This is less accurate, but will still get you very close.
You take the E-steps you currently have set. You tell your extruder to push 100mm of filament. You divide this by the amount of filament that was actually pushed (so 100mm/132mm would be 0.75)…you take your original E-step number, and you multiply it by that result - effectively this error-corrects until 100mm of extrusion is 100mm of extrusion from your machine.
Unfortunately, there are people who also do this while pushing into a hot end, or while they have some mechanical slippage, etc – and this ends up giving them an incorrect result, with a mechanical error causing them many headaches down the road.
@ThantiK woow deep thing thank you i will take time and do math.
With the nozzle within 1mm of the bed, move it in X and Y directions and make sure it stays at the same height from the bed. You should be able to test again at paper distance from the bed and get the same resistance when pulling the paper regardless of where on the bed the nozzle is. Where the high spots are will help determine what adjustments need to be made. That is assuming there are high spots.
Thanks for all the help everyone
The problem was me not reading the instructions for smootieware properly, forgetting to clear the override settings in smoothieware after rebuilding it, the delta thinking it’s shorter than it actually is and the raspberry pi’s octoprint eating its sd card, it’s now printing ‘ok’
