You defeated the purpose of having an all metal hot end by wrapping it in teflon tape. The purpose of removing the ptfe tube with having an all metal hot end is to reach higher temperatures above...

DO NOT ATTEMPT TO UPDATE THE DRIVERS ON YOUR QIDI TECH! YOU MAY BRICK YOUR MACHINE. The Qidi Tech uses a proprietary bios that will not allow for convential updating of the software. In order to...

I use 1/8" borosilicate glass. The 1/8" in my opinion is better because it reaches temp faster. With a glass plate, you want to use the preheat function as much as possible and then check your bed...

Have you done this and experienced it first hand?

I am looking to print nylon which requires about 250*C at the nozzle. Any recommendations? What is the limiting factor of mounting it?

Where did you get the knockoff hot ends? How are they working for you now? I am considering getting the E3D V6. Does it work with the Qidi Tech no problem? From what I have heard, the knock off...

So I was able to restore my "bricked" Qidi Tech with Sailfish 7.1 using Win AVR and the usbasp programmer over the 1280 ICSP port.

However, when I restored it, my original problem of the X axis...

I had this problem just before I bricked my motherboard. It may be a problem with the stepper motor driver. You may have a spare. If not, you can get a replacement on ebay from china for $3.

Hmm,

Well I had access to the motherboard before via USB through RepG. Did I even have to flash the bootloader?

Also, what I was asking was, Do both .hex files get loaded onto the 8u2 port?

The two pins on the motherboard. I am connected to 8u2. Is 8u2 where I load both hexes? Or do I only load the makerbot to 8u2? Or do I load atmega1280 hex to the 1280 pins or to the 8u2?

I got...

I lost Internet when I was replying.

I fixed the path for boot loader. Didn't realize that was your subfolder for the boot loader. I have the files in my C directory.

edit: you had it...

AH, okay I had to download windows 7 64 bit drivers for the USBasp.

I just tried your command line again and got the following:

avrdude: Device signature = 0x1e9389avrdude: Expected signature...

Okay I did some more reading. I am getting this error when trying to run that path: avrdude: error: could not find USB device "USBasp" with vid=0x16c0 pid=0x5dc

Thanks for the files. Would you mind pairing down the info for me? I am not using a at90usb82 correct? So that command line would be different. What AVR Part would it be using? ATMEGA8?

I bought these and have them connected. I am using AVR Studio 4 but am unable to connect.

I just got my tools for flashing my motherboard. Will dive in and hope I come out on top!

Does anyone have the qidi tech instructions they can upload? The instructions that come on the SD that...

I am able to control the machine through S3D and monitor progress. I am also able to print through SD card or over USB. I like S3D interface because you can see a history of prints and also have a...

Yes. You have to set up the machine as a flashforge creator pro.

I can give more detail later when I'm home.

its probably a part of a wholesale order that was damaged but not accepted as a return by qidi tech. Seller was probably already compensated for the damaged and resold it.

I just won another printer on eBay. A Quidi Tech II. It looks like it had shipping damage but the price was right and I couldn't be out bid.

Thanks for the reply. I ordered a set of 8825 to test. I figure a set is the price of beer so I just stayed in tonight to do some work on this. I'll of course update you all on the results.

So...

Will there be any compatibility issues if I swap stepper motor drivers completely? Looking at the DRV8825.

Okay just ordered those parts.

Do you know where I can get a replacement stepper motor driver? I don't think I have an extra one.

Yeah hence why I never attempted an upgrade. I wasn't even trying to upgrade this time but only reset the motherboard to default but somehow managed to brick it.

I'm actually reading that thread...

Ah yes I see them. Thank you. Looking for my spare. Unfortunately I screwed around in rep g with firmware. The screen is completely blank after resetting, powering on and off and disconnecting and...
