No it's not skipping without filament.

Thanks for your consideration
I have all you have mentioned, except for acceleration settings. I will look into that.

Higher print...

I went max out .75 on my DRV 8824, not 8825, that I had. .75a doesn't cut it. I put back the 4988 driver, and cranked it up. Once I get to .8a, the motor starts skipping doing a normal extrude for a...

Hmm. I couldn't find info on recommended current on my bulldog.

Does your bulldog still tock on micro stepps?

You see, I have been doing all these test without the bowden. Just pulling...

Apparently, to a thread I found, this behavior is normal if your only doing 1/16 steps with your motor, and printing at low speeds. So I replaced my stepper driver with a DRV 8825 which luckily I had...

Seems to go up to 1.5-2v before its too much. Going that high doesn't help. the slightest tightness on the drive gear causes a tock when moving the filament .1mm. The only thing that changed...

I greatly loosened the screws that tighten the drive weal on the extruder. It skipped less. So I pushed the drive weal so it had 0 pressure on the gear that drives the filament, and it didn't skip at...

I got a makerfarm 12 inch. With rumba board. Got it running with a bulldog lite. I had have extruder problems, and clogs and such. After breaking 2 heat breakers on my hexagon hot end, I switched to...

Got my new fan today. I replaced the nozzle with a new one. Torched the one I took off. And with the new fan, my Replicator 2 seems to be printing like the beast that it is so far. Extruder motor...

Ok, I ran a Ctrl V Print, and I got lots of stringing, and didn't like the detail. On that print I took printbus's advice and loward the retraction speed to 15mm/sec.

So I printed twin towers...

hahahahaha

Thanks for your response Sinful.

Ya, I only plugged in that fan for a few seconds. It didn't work. It's a 12v fan. I already ordered the fan form makerbot.

I tried to let a the printer run and...

Ok I'm starting a new print. Here is a link to the object in thingiverse if anyone wants to see it. http://www.thingiverse.com/thing:704409
I think the shift you refer to are the rafts that I didn't...

I have my hands on a i3v 12in from makerfarm. Have had it for about 2 weeks. Been doing tweaking this entire time. I'm using Simplify3d.

I've done thin wall test, and 1cm cubes, and such. But I...

I think you might be right Mjolinor. Maybe I just missed it before. The motor does press against the "heat block?". So it has to get hot somehow.

I had the motor running just hanging on the side,...

I took some pictures. I don't see anything wrong. Could it be the wire that heats up the nozzle, its next to where the motor would go. You can see in picture.

I think I need to check connections to the mothe board. I'll have to google how to do this. Not really sure what I'm looking for. But I'll check for abnormalities and burn marks. I'll post pictures...

I have worked with clogs before with the machine running, and never felt the motor get this hot. And yes, it does get hot fast.

Thanks for your reply 3dkarma. I'm going to do it once I establish some confidence with my new machine. I've seen people pop out really good looking prints with Makerfarms Prusa with little to no...

I have had my second 3d printer for about 2 weeks. An i3v Prusa 12in from Makerfarm. I noticed that it can't seem to get the quality finishes on the surface of my prints as compared to my Replicator...

I have been having extruder problems on my Replicator 2, and was making sure nothing was jammed and such. When I was resembling the extruder assembly, my hex screwdriver slipped and broke the fan. ...

I got it to work just by adding rafts it seems.

Here is what I printed without rafts.

With rafts....

I use blender. You can create a planes, and place them where you want. Then you apply a boolean modifier to the object you want to split...deleting the parts you don't want relative to the plane you...

Waiting for someone to come out with software that can automate slicing a large object in parts to reassemble. But I think more companies other then Makerbot should do it.

Thanks you very much wpilgrim.

Looks like the problems were 2 and 3 for me.

Played around with a few slicers and ended up buying simplify3d. Loving it.

Iv'e only had a problem with one...

Used Microsoft's model repair service here https://netfabb.azurewebsites.net/ , all my prints didn't have layers skipped so far. but printing the feet still skip the toes?

Any Idea why this could...
