Re: Heated bed options for a Prusa-inspired delta printer - 5 years ago

Using the aluminum plate with the magnetic foil definitely seems like a good plan. I don't really plan on printing ABS so the bed probably won't get above the 85oC for PETG. I'm not too concerned with the textured bed, but it might be worth trying that kick starter. As far as the bed size goes, the plan right now is to do 250 mm diameter print area with a 10 mm border for mounting. I think that's

That's in interesting idea. How well does it hold the bed on compared to the Prusa?

Heated bed options for a Prusa-inspired delta printer - 5 years ago

Hi all, I'm designing a delta style printer that takes a lot of design inspiration from the Prusa i3 Mk3. This is the first printer I've built from scratch, so I'm sure there will be several other posts I'll make about it. One of the features I really want to include is the magnetic removable bed. The print surface seems fairly simple, it looks like a 22 ga spring steel plate with .25 mm PEI sh

Re: Issues upgrading delta printer from Ramps Plus2 board to Einsy Retro1.0a - 5 years ago

QuoteDust This page for the Plus2 shows the gnd and +5v on pins 9 and 10 where as this page for the Einsy retro shows power is on pins 1 and 2 Good call. I cut off the tabs on the plugs so I could flip them around and at least it has power now, but no display. Looking at those schematics, it also looks like the TX and RX pins are in different spots too. Is that something that can be fixed in

Issues upgrading delta printer from Ramps Plus2 board to Einsy Retro1.0a - 5 years ago

I have a Flsun Kossel Delta printer that I'm trying to upgrade the motherboard on. It came with a Ramps Plus2 board. I got an Einsy Retro 1.0a board at a Lulzbot garage sale, so I wanted to put it into the Delta. I got everything rewired, plugged in, changed the board and driver types in marlin, turned it on, and not much happened. The fans start to run, but the LCD doesn't turn on and remai

Re: Touch screen options for printer using an Einsy Rambo 1.1a. - 5 years ago

Thanks for the reply. QuoteDust On the Einsy tx0/rx0 is available on tp25 and tp26 or directly off of chip u10 or you can use rx1/tx1 on j19 and change your serial port in the firmware to 1 (this will disable the usb cable) or you can use rx3/tx3 on Ext P2 and change your serial port in the firmware to 3 (this will disable the usb cable) Could you point out those sets of pins on a pictu

Touch screen options for printer using an Einsy Rambo 1.1a. - 5 years ago

I'm working on upgrading my Prusa i3 MK3 with a touch screen, but I'm having a hard time finding one that will work with the Einsy Rambo 1.1a. The only screens I've found are like the KINGPRINT 3D Printer Controller Board MKS TFT32, but that uses an 8 pin AUX connection which the Rambo board doesn't have. Does anyone know of a touch screen that can be used without too many modifications?

Re: Incorrect scale in XY direction - 6 years ago

Thanks for the tip. I recalibrated it and in the process found several other issues with the printer and the firmware, fixed all of them and found a post that said to proportionally adjust the delta rod length. Hopefully that's the last bit of fine tuning I need to do.

Incorrect scale in XY direction - 6 years ago

Hello all, I recently updated my firmware to the newest version of marlin on my FLSun Kossel Delta Mini printer using this guide; After I followed this and the calibration guide I printed the Advanced Delta Printer Calibration from Thingiverse. When I measured the distance between posts, it revealed that the part was roughly 2.45% smaller in X and Y but Z was the correct size. I tried to foll

Auto Delta Calibrate is not working properly - 6 years ago

Hello all, I recently updated the firmware on my Flsun Kossel Delta Mini using the guide found here; When I tried using the Auto calibrate, it doesn't work properly. It lowers the Z around 50mm, moves the effector around x and y seeming randomly and erratically. Here's a video so you can see it's movement; The values is gives me are not at all accurate but the sd it gives me is 0.00. I can'
