I tried both the Slic3r default speeds 30mm/s etc and the same speeds I've been running my Prusa and Ecksbot at. 48 shells, 60 infill, 160

I was told that the weight of the drive motor on the carriage would be a problem. But I had to try anyway.

Some of you may have seen my Rack & Pinion Y drive before.
It took me some time, and lots of thought, but I've finally put together an X Rack & Pinion drive.
You can see it in action here:

The files for the X drive are on Thinkiverse here:

I'm turning 50 today, and everybody tells me it's a big deal!
So, to help celibrate, I'm putting all the plastic spools at Glankonian Protoforms on sale!
This is a great time to try out our new stock of 1kg 3mm ABS plastic!
I'm only turning 50 once, and this sale will only last the week.

I've found a supplier of 1kg spools that I like.
I was first attracted by the packaging, and the plastic didn't disapoint.
So, I'm stocking some.

three things you could try.
1. Set the extrusion width to your nozzle width in the advanced section in Slic3r.
2. Use only 1 parimiter for this print. This gives the slicer more space to actially fill in.
3. Make sure extra paramaters is switched off. Enforces 2.

Defenatly extruding too much.
Standard Questions:
1. Have you calibrated your E-Steps?
2. Did you measure the actual size of your filament and enter that into your slicer?
Filament width very not only from different makers but also different rolls from the same maker.

PLA can be made flexable in boiling water.
You can also do a quick burn test with a lighter.
PLA will smell sweet. ABS Defenatly not.
PLA seems harder to burn, and my sample just seems to caramize while burning.
ABS turns black and gives off black smoke.
Hope this helps.

I've never run the Pololu's without a heat sink. Ecept for when an erant wire or such would knock one off. usually resulting in the loss of the Pololu.
I don't think you can get enough heat disipation without a heatsink. Even if the voltage is perfectly set.

Sounds like what you guys need is some kind of hose or snorkle arangement to allow cooler outside air to pass the hot end and then exit the 'chanber' without mixing with the inside air.

Got a new RAMPS board and swapped it.
Thermister not plugged in still reads 90c and now 92c pluged in.
I'm guessing the RAMPS just passes the connections to the Arduino and it's something there causing the higher reading.
So, I'm guessing I need an new Arduino Mega and have an extra PAMPS.

One of my machines started registering room temp on the hot end as 94c.
Previously aprox. 28c same as heated bed.
Seemed to work anyway, for a while.
Had to clear a jam in the J-head and decided to check the thermistor at the same time.
Pulled it off the RAMPS and the temp dropped to 92c!!!?
So, I'm thinking the fault is in the RAMPS board rather then the thermistor.
Is there a way to fix th

Usually when I get that, I just up the head temp a few degrees and it works fine.

This is my method.
Start cold.
Set temp to 230C or about for ABS.
As the temp passes 170C apply upwards pressure on the filament. Usually pulling gently on the filament with one hand and gently turning the gear with the other.
Somewhere between 170C and 200C the ABS will let go of the extruder and come out cleanly. If done right you will see a short smooth section on the end.

Advice I've heard that works for my Prusa and Wallace8mm machines is to tighten the belts to a low pitched twag.
Huxley, being a smaller printer, I can't be sure.

There must be a short somewhere.
I've occasionally shorted wires by accident working on my printer with the power on. (Doh!)
The ATX supply always shuts down before any damage can occur and won't re-start until switched off and on again. Hopefully with the short sorted.

jbernardis has it right.
The controls are head relative. If the head doesn't more in the Y direction (Most printer designs) then the bed must move in the opposite direction.
The Down on Pronter face means Move the Head down to the front edge of the Bed.

Have you checked your filament width?
I've had a roll of filament change average width over the length of the roll and others melt temp.

For Quality plastic in Canada I would have to recommend EckerTech. I have used several rolls of there plastic with no serious issues.
In fact I stock it in my own store.
US I've tried MakerBot and 3DPrinterStuff. Both are Good Quality.
Ultimachine is presumed to be as good as the above. I haven't actually use any yet.

I'm glad you found it!
Turns out my Z stepper driver was shot (again...) from the heat sink roaming around.
Regarding second machine, be careful, they are like potato chips. Can't have just one.

I'm using Kapton sheets on mirror glass. Sticks better to the glass than to aluminum plate.
Works great for me and I can re-seat the sheet if I do get lift bubbles under it.
I did a video on re-seating the sheets.
Applying and re-seating Kapton Sheet.
I find it's more durable than the tape also.

I've been to the Toronto 3D Printers group several times.
Always good to see new and different printers there. Talk with the regulars and help the new people.
The best is when I get to talk about my latest builds/creations.
They're a great bunch.

That sounds like your Z-motor driver on the RAPMS(or other) board may be over heating.
It'll just pause long enough to cool down.
I ran into that when I first tried a real print on my Wallace. The cubes were small enough to not be a problem. Bigger prints soon had problems.
Usually when things are going wrong, I pause the print and raise the Z by 20mm. The over heating stepper driver caused th

Not sure what you mean by 'nice line profile'.
In my case, I'm using a Wallace design here and the Z motors are only mounted on one edge.
After I tightened the Z-Coupler that had gotten loose, I noticed the motor oscillating up and down as the rod spun.
I figured the motor must have been on an angle (being held only by the edge) when I tightened the coupler.
So, I designed a set of Z-motor su
