Re: delta patterning on vertical surfaces - 6 years ago
Quotehercek Quoteredscorp If this is not a 8-bit math, can it be stepper/driver precision problem. Will activation of 1/256 steps on 2208-UART solve/reduce this kind of effects? A common cause of imprecise movement at low speeds/accelerations is bad stepper driver / stepper combination. Typically, the problem is slow decay mode of a "dump" stepper driver with high inductance and low resistance stby redscorp - Delta Machines

Quotedc42 Axis microstepping greater than x16 doesn't usually improve print quality, but it does make the printer quieter. Some users report that extruder microstepping above x16 can under some conditions slightly improve print quality. Interesting. Thanks!by redscorp - Delta Machines

Quotedc42 Quoteredscorp The Duet WiFi board will not do it for me, because I use diamond hotend which need 3 extruders, which means 6 stepper drivers in total. Can mentioned RepRapFirmware be ran on MEGAs or re-ARM? Both the Duet WiFi and Duet Maestro have expansion boards available. For the Duet WiFi and Duet Ethernet there are the DueX2 and DueX5. For the Maestro there is a 2-driver daughter bby redscorp - Delta Machines
Re: delta patterning on vertical surfaces - 6 years ago
Quotehercek You have some obvious ringing there which is unrelated to 8-bit electronics. You have way too much elasticity in the printer for the speed/acceleration you are using. The rest seems to be more like a backslash problem ??? If you think you have problems with poor performance of your 8bit MCU then just lower segments per second to about 80 and print with speed below 100 mm/s. Or evenby redscorp - Delta Machines

delta patterning on vertical surfaces - 6 years ago
Hi! I own anycubic kossel plus. This one is originally based on trigorilla board (merged mega+ramps). The only upgrade I made, I've installed 2208 drivers for silent operation. When I print vertical surfaces I often notice geometric patterns on the walls. This patterns are reproducible by printing same g-code again. My assumption is this is because of 8-bit board math vs complex delta kinematic.by redscorp - Delta Machines
