Re: LPC1768/1769 Port of RepRapFirmware v3.1.x - 4 years ago

QuoteMKSA The MKS in addition to be a pain with the Ethernet, uses 8825 stepper drivers soldered in place. And the slow / fast decay pin is fixed and not externally accessible. Which leads to all kinds of problems. From what I learnt in the github wiki the SPI pins are not externally accessible but through a level shifter. Only solution to get this working is to unsolder an RC lowpass on some ot

Re: RepRapFirmware 3.0 port for LPC1768/9 based boards - 4 years ago

Quotegloomyandy I doubt if that TMC51xx support will work without a reasonable amount of work. The Duet 51xx support expects to use hardware SPI and it is all for a different set of processors (various SAMExx versions) which have a different hardware SPI unit to the LPC17xx used by this port. It certainly won't be just a case of setting the compiler option. What aspects of the 5160 do you need? H

Sorry if I've missed that, but is there already support for TMC5160? I've ordered the new SKR 1.4 Turbo with TMC5160. Those have SPI or UART interface. EDIT: Okay seems like it: src/Duet3_V06/Pins_Duet3_V06.h:#define SUPPORT_TMC51xx 1 I'll investigate how to enable those when I have the board

Re: Questions about TronXY X5SA - 4 years ago

Tronxy X5SA with the chitu_f103 board is now supported in the bugfix-2.0.0 branch of Marlin. Including the bootloader.

Re: Kossel Delta xxl build project HELP - 4 years ago

Are you printing from SD card or octoprint? the serial bandwidth is limited. Try to set the resolution to at least 0,01mm.

Re: Delta printer ball joints, let's talk! - 5 years ago

QuoteI wonder what it will take me to injection mold them of POM or PTFE Thanks for your update. I thought about 3d printing the plastic cage. Don't laugh I have some POM at home. This stuff is difficult to print and dangerous, but sippery. The inner ball needs to be pressed into the cage anyways, so inaccuracies might be evened out. What do you guys think?

Thanks hercek, I'll try them out anyways. I hope I'll remember this thread and report

Re: Delta printer ball joints, let's talk! - 5 years ago

I've had the same problems with magnetic joints. I thought it was just me. I've 'fixed' the problem using long springs to attach each pair of rods to the effector. The extra holding force helps. But with fast printing the plastic deposition is sometimes uneven which leads to bumps. Those get evened out with time. But with magnetic joints the effector comes loose and the print is kaput. I've ord

Re: Klipper: Configuration for Anycubic Kossel 218mm rod version - 6 years ago

Thanks! I've switched over to a MKS SBase v1.3. And I've realized, that it's impossible to get clean prints with Octoprint. I think the cause is that the bandwidth and latency of the usb-connection is just not good enough which results in small pauses. So I've blobs all over my prints. I can fix this by printing from SDcard. But then I have other problems like the ringing DVR8825 stepper drivers

Klipper: Configuration for Anycubic Kossel 218mm rod version - 6 years ago

Hello, I'm trying to configure klipper for my anycubic kossel. The biggest problem is translating the geometry from marlin 1.1.8 to the klipper configuration files. Does anyone know how to calculate the values from a working marlin config? This is my marlin config: // Print surface diameter/2 minus unreachable space (avoid collisions with vertical towers). #define DELTA_PRINTABLE_RADIUS 90
