Printing Weirdness
What I have done is tried to give Sprinter, to see if I could replicate the problem with that firmware, however, Sprinter, even with the exact same setup from Marlin, Sprinter refuses to read my hot end via a MAX6675.
Marlin does read the MAX6675 just fine.
In 5 days I will be showing off the RepRap project at the Tangleball Makerspace ope

Ditto
Also makes it vastly more convienent whent he supplier is in the same city -> Vik Olliver, great chap
Tangleball members love the luminescent filament.

I managed to fix the Z height problem, had to reduce the feedrate, homing feedrate and acceleration. Just the buffer to sort out now.

I know what you mean, however when trying to word it, in such a way, to not get mixed up between the gcode of the sliced model vs the gcode that gets sent via clicking in PronterFace.
There is the buffer in the firmware to consider, and although I don't know how many lines of gcode it can store, there could have been an issue with the buffer, in some way. Like it could handle 1 or 2 lines just f

There is no loose connections.
I use a Thermocouple instead of a thermistor.
The cold extrusion cut off has been reduced to 150C to enable me to print at a decent quality, without a fan. Normally it is 170C, which leaves a glob that resembles a print and not much else.

Using Marlin V1.0 RC3
RAMPS 1.2 with onboard MAX6675
Slic3R V0.93
Nozzle 0.4mm dia
Filament 2.9mm dia
Layer height 0.3mm
I have two problems, that I hope someone could possibly enlighten me on please.
When doing a print, PronterFace shows this as feedback part way through the print
Marlin 1.0.0

Hey, Thanks Sound/Traumflug,
I may have inadvertantly fixed that issue, while finding a solution to another.
The PID I had set for my hot end, which was in the defaults for MakerGear, was found to be not aggresive enough to keep the hot end hot when the filament is pulled through, causing the barrel temp to drop to about 175-180C, NOT gcode driven but rather using PronterFace to extrude plastic

I know it is deprecated, but obviously not with Slic3r
I checked last night in the firmware, the M109 code, it appears to work exactly like M104.
After work I will check out the actual behaviour on the RepRap.

After rummaging through very old topics about Marlin and M109 gcode, I am left wondering if anyone else has encountered this problem.
I preheat the extruder to 180C in PronterFace,
Using a sliced model with Slic3r (V0.92 and V0.93)
Print stops right after homing axes and the extruder heater is turned off.
Seems like Marlin (RC3 on RAMPS 1.2) is shutting down the extruder when an M109 is reciev

Not true, I spent months finding a modern version of FiveD that had the required features that I was after, was able to compile and run it without a problem (before TeaCup).
Someone was "cleaning up the code" whilst supporting newer electronics, and royally screwed up support for Gen3.
It's working now, just!
I suggest that he/she try out TeaCup, as that is now the most up to date version that

This is something I will try out.
If anyone still remembers Darwin, it had a belt tensioner
I plan on doing the same for chain drive.
Ladder chain is good, but not available in do Zealand. Tamiya do chain, as does Vex, not to mention common bicycle chain.

I've also made the gen3+ board from veroboard/strip board
I won't be using that board, as I will use EasyDrivers from sparkfun, switching out the old 1/2 step drivers for 1/8 step drivers

The old firmware for generation 3, was quite bugged to support newer hardware and not regression tested with Gen3.
Also you will need to set in firmware to disable any acceleration.

Are you using the 1.2 motherboard and extruder board?
Well believe it or not, I am still using my generation 3 electronics, but I hope to ditch the old firmware, in place of Marlin.
From comparing pins, you should just be able to use just the motherboard to control all 4 steppers, and thermal management.
The daughter board mentioned in the previous post will sort out the thermal and extruder

I think I have solved my mystery.
I used the default vaules from Sprinter to give me a ball park figure to calibrate my old machine with.
Believe it or not, my old Sells Mendel still worked - okay for the past 2 years
Last year I started working on my own Pololu shield, before Johnny, but life got in the way and it's 1.5 years later, board done, and it was time to replace - wait for it.

Hello all,
Could someone please tell me what to set to have a stepper motor on X and Y turn properly?
Currently, the wiring is good, but the motor is moving back and forth.
I've tried reducing the acceleration parameter, still doesn't work
I've tried reducing the motor speed, still doesn't work
I'm sure i've missed something, but not sure what
The board is RAMPS 1.2 derivative of my own, wher

Yes it can, my version anyways.
Uses the Max6675.
I started the project a year ago, and I've only just got back to it.

Almost Frankenstein in a way, yes!
From now on, when Tangleball here in Auckland, New Zealand has a Maker day, or hosts a Software Freedom Day, we can show how the open source project has evolved, in a very short time span.
But the old man needs a new ticker and pen to draw new things that he'd never would have seen otherwise.
Okay, too many metaphors, but you get the gist.

Yesterday during the Tangleball makerday that we regularly have, Vik Olliver dropped off the "Grandad"dy of all RepRaps.
It has seen better days, and i'm honoured to have it at the maker space, and get it back into operation again.
The whole thing is twisted, doesn't have an extruder, or nozzle, no controller, and has missing parts.
It does have a heater barrel, stepper drivers for all axes,

As I near getting pretty decent prints, i'll be printing parts for anyone in Auckland that wants them via Tangleball
I am also developing a better version of RAMPS in my spare time, though not quite ready yet. One thing that I am thinking of is whether people are going for Prusa design or Sells, current thinking is to see if the Prusa can be made with a single Z axis motor. This would mean 5 p
