Bit of an update! I decided to throw some more voltage at my stepper drivers just to experiment some more, they didn't look like they were missing or skipping steps and they sounded fine too BUT after setting my steppers to .35 it seems my lines have straightened right out, not absolutely perfect but definitely good enough for now and to allow the printer to be usable. I decided to set my extruby silverbullet - Delta Machines
Do you have the jumpers on the pins under the stepper drivers? don't laugh, heaps of people do it and it has the same symptoms you describeby silverbullet - Delta Machines
Thanks for giving me some more ideas to look at I have checked pushrod lengths, i made them on a jig they are .5 of a millimeter within each other, pretty much close as humanly possible lol. I spent some more time on it after work today and i did notice the carriage on the x axis was a little closer to the vertice, i don't have any washer on any of them but i flipped the bearings and the carriby silverbullet - Delta Machines
I was using a E3D-V6 clone and i noticed the thread for the heaterblock was on a bit of a slant (so when the block is threaded onto the heatbreak the block sits on slight angle and of course the nozzle too i assume, not much but noticable enough to throw the nozzle off probably a mm or two...would this be causing my issue? Either way i have ordered a genuine V6 and it should be here by the end oby silverbullet - Delta Machines
Quotenebbian SilverBullet, Welcome to deltas. They are frustrating, and often difficult to get to print straight. It's unlikely to be missing steps. More likely is one or more of the following: * Towers not parallel * Towers twisted * Bed not at 90 degrees to the towers * Diagonal rod value in firmware not matching physical measurement * Delta radius in firmware not matching physical measureby silverbullet - Delta Machines
I have been spending some more time going over the delta checking everything once again. My corners are printed and i think my "X vertice" is twisted off axis by a couple of mm. I noticed this because the clearance of where my belt runs through the carriage is not the same as the other two carriages, if i twist the x vertice with my hand gently then the clearance opens up to match the other twoby silverbullet - Delta Machines
Hi yes i have checked and set all Vref values on stepper drivers with a multimeter and i have checked grub screws on motor pulleys...all fine. Gotta say though i'm pretty stumped as otherwise the delta prints beautifully, it doesn't make sense to me at all at this stage as to why it's happening and not affecting anything else print result wise.by silverbullet - Delta Machines
Hello Folks Last week i completed building my first delta...a kossel mini! It was certainly a lot of fun, i printed all the parts and sourced everything else myself including making my own carbon pushrods in a jig to ensure they are exact to each other as possible within reason. I am running Marlin firmware, i bought my electronics from Sintron so i also got a hold of the firmware they use soby silverbullet - Delta Machines
