Been a while since you posted here TimRuffner? What was your previous username then?

Re: Host install problems. - 14 years ago

Why would it be requesting that much RAM? I run the host software on a several year old computer with 1 GB of RAM under Windows 7 and have no issues at all.

Re: mixing things up - 14 years ago

My motors (with Gen 2 electronics) are permanently enabled. It's not a big deal, and doesn't hurt anything.

Re: Wades Question - 14 years ago

I have three NEMA 23 steppers from alltronics, they were only $17 a piece and very powerful. They're working great and seem to be very high quality.

Re: 6v steppers - 14 years ago

I run 0.9 degree 3 volt steppers with 12 volt supply, and have no issues at all.

Re: frosted glass build-platform??? - 14 years ago

Are you going to print PLA or ABS? For PLA you don't need a heated bed, and can just print on blue painters' tape on top of any flat stiff surface.

Re: First print..! - 14 years ago

I print PLA on blue painters' tape. It works great!

Re: Geared Extruder Nozzle - 14 years ago

I wish I had known you were going to make these before I bought one of your nozzles I do have to say though that your machining is excellent, and so far the nozzle I bought is working great. To everyone else, I would definitely recommend doing business with reifsnyderb.

Re: 3mm PLA Filament - 14 years ago

I ordered some 3mm clear PLA from them a bit ago. They have good prices and ship quickly.

Re: Extruder barrel questions - 14 years ago

To prevent PTFE bulge, just get a 1/2" copper pipe connector. It fits snugly around the insulator (I actually had to hammer the insulator in with a soft-faced hammer). That will keep the PTFE from bulging and should cost less than $1 at any hardware store. You might need to file down the stops if it has them on the inside.

Re: Where can you get PLA? - 14 years ago

How about here? I just ordered a 5 lb roll of PLA in natural color, should be here today.

Re: stepper motor wiring & color codes - 14 years ago

This isn't a forum for helping random people from the internet use stepper motors. This forum relates to RepRap. If you want help with a specific stepper for something other than RepRap, you really should try Googling it or asking somewhere else.

Re: Bootstrapping Mendel with McWire. - 14 years ago

I am only able to get about 4 mm/s out of my McWire. I'm not quite printing yet though. I plan on converting it to a belt driven X and Y axis, which shouldn't be very difficult. I'll post back if/when I get it done.

Re: McWire Cartesian Bot v1.2 screw sizes problem. - 14 years ago

The holes are sized to be tapped. Once you tap them the screw will fit perfectly. If you want the screws to instead go through and secure with a nut, you will need to drill them out to the size of the screw.

Re: MakerBot Plastruder - 14 years ago

You just have to check back frequently. It's been in stock more than a few times in the past few months. I don't know of any other ready-made extruders, but I have seen some made that are really simple.

Re: McWire Extruder Mounting - 14 years ago

With the McWire, it ends up being 1.25 mm per revolution for all three axes, which is 32 times slower in the X and Y than the Darwin. Hence the reason for me switching it to belt driven. It looks like it will be quite simple to do, I just need to get some belt and pulleys.

I never get emails from them when things get back in stock, despite making sure I had clicked "Sign up to get notified when this product is back in stock".

Re: McWire Extruder Mounting - 14 years ago

I have both a complete McWire and a complete MakerBot extruder. I haven't gotten it mounted yet, but will most likely use some angle aluminum. Also, I will be converting the McWire to belt driven X and Y axes, as the screw drive is just too slow for reasonable build speed. I'll document both on my blog when I have time.

Re: US source for 2.54mm screw terminals? - 14 years ago

1/10 inch. I'm pretty sure that's a standard screw terminal.

Re: Welcome to the new subforum! - 15 years ago

This seems like a good subforum to open up. I'm just about to the point of getting my RepStrap printing, I'll start posting here with my issues/successes.

Re: PWM driver extruder problem - 15 years ago

sounds like you either have a short or are trying to pull more current through the PWM than your power supply can handle.

Re: atoma ring - 15 years ago

I've never seen those before. Pretty cool!

Re: casting aids for metals - 15 years ago

That's exactly how Jay Leno uses his Dimension 3D printer to make metal parts for his cars.

Re: gen 3 electronics and z-axis - 15 years ago

I'm sure someone else can chime in, but I remember there being a setting to enable the motors when they are not being moved. Unfortunately I cannot remember where it is.

Re: Alternatives to the toothed belt - 15 years ago

^^ what I would like to do is get my machine running as-is, and print a couple pulleys to work with ball chain. I've been trying to find some pre-made but haven't had much luck.
