I am currently using Gen3, although am also developing a better RAMPS, one that virtually anyone can source parts for, except the polulu drivers.by Grogyan - New Zealand RepRap User Group

You are my hero. The guys at the makerspace Tangleball, and myself have spent weeks trying to get the code working to a state that is reliable for calibration, I had been using firmware from 20100806, but encountered a serious bug that I know got fixed much later on, so upgraded it, and had a whole new set of problems, and I couldn't work out what the code was doing. But here we are, and I get "by Grogyan - Reprappers
I will be trying the new flow rate as soon as the new firmware gets fixed, previous version stopped printing after a few layers and crashed, an old bug. For me the new flow rate should be about 75.24 e steps per mmby Grogyan - Skeinforge
I have a RepRap at Tangleball Makerspace needing calibration. Gen3 electronics at the moment, but may be replacing with my own RAMPS variant (uses the MAX6675 as the thermocouple conditioner).by Grogyan - New Zealand RepRap User Group
I should have posted a long time ago. I am currently busy workin on getting my current RepRap working under Gen3, so much time that I still have not got around to getting a PCB fabbed. Yes I am slow, and I do think about it every time I work on the RepRap every week. Life is busy! But I have not forgotten about this little project. I see that JonnyR has long since added to his a second extrudby Grogyan - RAMPS Electronics
Cheers everyone, I've been sick for the past two weeks, I hope try out your suggestions this week.by Grogyan - Skeinforge
I couldn't be bothered the wandering around, and ordered them from RS components, which the NZ site imported from Australia/UK. It is expensive, So if any locals have tried printing a chain, this I reckon would be a better option. It's on my list of things to try once my RepRap is calibrated.by Grogyan - New Zealand RepRap User Group
Could someone please upload here known good settings for Skeinforge 40 and above using Gen 3 electronics, and Wade Extruder? I spent weeks getting a square blob of plastic, and tonight, Skeinforge decides it wants to move the head 10mm left from the raft for the first layer. I am using a 0.4mm nozzle with e-steps-per-mm set to 1.39 for the wade extruder 3500 flow rate 0.35mm layer height 30mm/sby Grogyan - Skeinforge

It is for debugging why serial comms stopped working yesterday. Does the baud rate matter? I did try 9600 and got no response on power on, so I thought that there may be a command to send to establish basic comms.by Grogyan - Firmware - mainstream and related support
Just a quick query, as I had been beginning to test my electronics at the local MakerSpace open day, Vik unfortunately was busy and unable to help. What is the series of commands that I use to communicate with Gen3 electronics with the 20100806 formware, through HyperTerminal? Thanksby Grogyan - Firmware - mainstream and related support
Think about it for a moment, wipe or deposit silver paint, use the ion beam to fuse silver into the plastic once it has passed through extrusion? Just an ideaby Grogyan - General
This I believe is exactly what Adrian has been looking for. Someone should send him an email so he can follow up on this!by Grogyan - General
I have created a page, much of it is copied from the original page. I will update it, or anyone else can, as time goes by and board has been thoroughly tested. My apologies I have to log right now, Christchurch earthquake, I live in Auckland.by Grogyan - RAMPS Electronics
Should do, all that needs changing are the pins.h and the config.by Grogyan - RAMPS Electronics
Just remembered to do this on the way home from work today. Will let you know when the files have been uploaded.by Grogyan - RAMPS Electronics
Forgot to post, update. My version has finished being designed 2 weeks ago, but I do not have any money or a RepRap or transfer method to fabricate the board. I have also been busy, both at home and at Tangleball and forgot to upload the design. I may remember tonight after work however if someone really wants it ASAP then please pm me, to remind me to upload it.by Grogyan - RAMPS Electronics

BakeLite is resistant to much higher temps. For my reprap I bought a frying pan and turned its handle (bakelite) into a thermal break. Initial tests included using a naked butane torch flame on the plastic, no deformation.by Grogyan - Mechanics
Anyone know of a reliable source of fender/mudguard/penny washers other than steelmasters? Anzor no longer stock them.by Grogyan - New Zealand RepRap User Group
BakeLite is also useable and cheap, used for saucepan handles.by Grogyan - Mechanics

No! The idea behind thermocouples is that it is the right way to do temperature monitoring for the extruder hot end. Thermistors are bad for this and WILL fail! Because they are not designed for continuous use at high temperatures, approx 150 degrees continuous, which is fine for a heated bed. It is a fundamental called 'thermal run away'.

A lot of those pics are from the ZCORP machine which uses powder. You can if you want to, use a small nozzle, in the region of 0.25mm dia as opposed to 0.5mm dia standard.by Grogyan - Reprappers
You can use the breakout board, however you will need to wire it up to D50 to D53 on the Arduino Mega, as those are the pins that are addressed for in the SPI library. I am currently in development of having a native MAX6675 on the RAMPS board. Was working on it a bit more this morning, and it is nearly ready to go out for fab.by Grogyan - General
Made more progress, just got to make a new fuse part for the library, then the board is off to get fabbed.by Grogyan - RAMPS Electronics

Have you considered using bicycle chain? Having a printable chain and sprockets is on my list of things todo when my printer is up and running. Belts aren't too expensive, i'm buying mine through RS.by Grogyan - New Zealand RepRap User Group
