Re: RAMPS, TMC2130s, and LCD

http://up.picr.de/31439177fu.jpg As I personally don't use a SD Card with my 12684 and always found it a bit annoying to have some unused pins by using the Smart Graphics adapter I replaced it completely so only wiring the 12 pins needed for LCD to get the AUX3 free. After having the LCD functional...

Re: TMC2100 - Stepper whining

I am running the TCM2100 for about a few weeks now and these are my experiences. I have the logical 5V version from watterott. As I received my bundle I solder one driver with all pins so without the jumpers set on a RAMPS CFG1 is pulled to GND and the stepper is running in spread cycle. The second ...

Re: Video guide for Unified Bed Leveling (UBL) in Marlin 1.1?

I'm currently analysing the UBL feature within the Marlin code. I haven't been able to test it so far as my Anet A8 has a ATMega128 based board and the flash memory is just to small to get UBL activated. At the Moment I'm completly rebuilding my printer with a 2040 Alu profile Frame and a Ramps1.4 a...

Re: Flex Filament with lowest shore hardness

I understodd your suggestion, I'm already printing injection molds with ASA. But still as I might have to test 10-20 different designs until the final one is found, it's easier to print them in TPE and once the design is found convert it into a mold for small series production

Re: Flex Filament with lowest shore hardness

Thanks for your suggestion, I already do injection molding especially for high temperature treated part with silicon. The TPE parts I'm going to print are not stock OEM replacement parts, most likely they are custom tuning parts for race engines. To use directly printed ones is just amatter of fact ...

Re: Flex Filament with lowest shore hardness

Ok thanks for that tip. At least it's clear that this won't work in my Bowden Setup. Mext I will try Ninjaflex as there I can get 50g probe first. Maybe that's already soft enough. Even the 98A TPU that I already printed might do the job, it's just a bit harder to get it installed in the motorbike f...

Re: Oil or lube suitabele for lead screws and linear rods

Hi, on the lead screw I use the all purpose oil Ballistol. I use these on most of my application like Motorbikes, Weapons. Linear rods is something different as I use IGUS bearings I don't use any lube at all. With ball bearing I would not go with oil but better grease into the bearings, even there ...

Re: Trimmer Line as Filament?

I bought 2 different 15m rolls from german DIY stores Hagebau and Obi. I don't have any kind of measurement mechnism to check on the whole lenght. I took 30 random reading with digital calipers over the whole 15m lenght. Both Trimmer lines were rated as 1.6mm. From 30 readings 20 were 1.65mm with a ...
