Topic: Guestion on repetier host and fan problems

Ihave an sd-3 its been out of commission whiole waiting on a new heatsink and fan i have the new parts installed and did a quick modification for a fan on to the print head to improve the parts printed. the fans do not work now even though they should.

i've gone through leveled the bed checked everything out. I need to clean and regrease it

but i'm looking for the latest version of repetier-host for the solidoodle 3 and any links to the firmware updates. is there anyone that can assist me?

Re: Guestion on repetier host and fan problems

What have you connected the new fan to? How has it been wired? If you want a gcode-controlled fan (and have wired it to the board) your instinct is right, you'll likely need to update the firmware to make it work.

A solid firmware for the SD3 is here (it's a stable and functional version; the Marlin project it's based on is in a bit of a state of mad development at the moment so I'm pretty sure you don't want the "latest" version...).

Search the forum for the procedure to update the solidoodle board; I'd guess you have a SD printrboard rev E if the machine isn't very old.

Good luck, if you have trouble performing the update (and searching isn't finding the answers!) then let us know. smile

the new fan is wired to the cooling fan attached to the heatsink

So you have a Sang board and it is fairly easy to flash the firmware assuming it has a Bootloader.

Re: Guestion on repetier host and fan problems

With the Sang you can connect with arduino (check the WIKI). Simply try and upload the firmware of your choice by hitting reset on the board and the upload button in arduino.
If it works you have a Bootloader.
The instructions in the WIKI should match up with your board fairly closely.
You'll want this firmware https://github.com/ozadr1an/Solidoodle- … in_v1_beta

Re: Guestion on repetier host and fan problems

The heatsink fan on the extruder should run continuously. If you've wired the nozzle fan in parallel with this, it should also work continuously. If you're using PLA, this will be great, but might create adhesion and warping issues with ABS.

If they're not running now, check your connections, check the wiring. Get a multimeter, and check that there's voltage where there should be (e.g. 12V between red and black wires on each fan).

The firmware update won't be able to affect whether the fan runs or not, unless you wire the fan to an output controlled by the board - in this case I'd recommend only controlling the nozzle fan; the existing extruder fan should probably run continuously still...

Yup, use the firmware ward suggests. I keep getting the lawsy and adrian branches confused haha.
