Re: Converting Mini to CBD Chitu 3.1 board

I have been using simplify3D for a few weeks now. It is nice to be able to have prints come out as good as the original UP software.

Re: Converting Mini to CBD Chitu 3.1 board

Well I changed it out to a Ramps/Arduino and I am up and printing in less than 4 hours including wiring, software and problems. Holy cow I cannot believe how terrible the Chitu board is. Granted I may be part of the problem but the Ramps is producing perfect models so I don't care if I was part of t...

Re: Converting Mini to CBD Chitu 3.1 board

I have never see anything quite as bad as this Chitu 3D printer board. This will be the last post I will make on this piece of garbage so here is the final email I sent to the maker of the board. "I finally got my new extruder built and have been attempting to test the Chitu board for most of the da...

Re: Converting Mini to CBD Chitu 3.1 board

I have completely given up on this until I get my new MK8 extruder from China. I am just sick and tired of messing with the Mini extruder. I wont give up on the Chitu board until I see how well it works with the MK8.

Re: Converting Mini to CBD Chitu 3.1 board

I like the MK8 only because it is a solid basic affordable platform to build a good direct extruder from. You are right the MK8 has a poor hot end but it is enough better than the UP Mini hot end and extruder that it is slightly more usable. I used an MK8 stepper and mount to adapt a Hexagon hot end...

Re: Converting Mini to CBD Chitu 3.1 board

Finally got the board set up to work with the Mini configuration. The UP Mini is bassakwards from a reprap machine in that the end stops are at the max travel points of each axis. There are provisions in the firmware to account for this but figuring it out was a challenge. The text in the firmware i...

Re: Converting Mini to CBD Chitu 3.1 board

Got the new board yesterday and it works. I am working on mounting the LCD and considering where to mount the giant ATX power supply. There is a lot of little things to consider when replacing the UP electronics mostly because of the design of the UP machine. There is no thermistor on the heat bed s...

Re: Converting Mini to CBD Chitu 3.1 board

Specs wise it looks similar, physically it is a lot different. My replacement board is on the boat from China and in a week we will hopefully see some progress. I need to get the Mini back up and running.

Re: Converting Mini to CBD Chitu 3.1 board

Email number 40 looks to be the magic number. They finally relented to sending a board even though they wanted me to keep testing. I will see if they send a prepaid shipping return label or not. It took me giving them an ultimatum and threatening them with spreading the word about their appalling se...

Re: Converting Mini to CBD Chitu 3.1 board

41 emails and counting. They obviously do not want to replace the board even though a warranty is listed on the purchase. I still hesitate to condemn them totally but I am getting very close to pulling the plug on this one. The seller is 3dfilamenta.com they are based over seas and so far are not go...

Re: Converting Mini to CBD Chitu 3.1 board

We are at 36 emails and as many or more pictures. We are going in circles now and the outcome is getting clearer with every email. I will play the game until the end but it isn't looking good at this point. I am also convinced that they have no idea how their board works nor do they know how a stepp...

Re: Converting Mini to CBD Chitu 3.1 board

Been going back and forth all day with this company and they wont admit the board is bad. This is not looking good. They told me they put my firmware on one of their machines and it didn't work therefore it has to be a good board. What kind of BS logic is that? Unless they put it on an UP Mini it su...

Re: Converting Mini to CBD Chitu 3.1 board

I am going to keep everyone up to date on the problem resolution process of the Chitu board since customer service is a part of all of this. So far I am getting the dance around from them by having me check all the brain dead things like the wiring, firmware etc. It is definitely a bad board since n...

Re: Converting Mini to CBD Chitu 3.1 board

Seems I have a bad board. The extruder part of it will not work. I connected the extruder motor to the Z axis and it works good so I know the motor is good. I am in contact with the manufacturer so we will see how that goes. I have tried everything concerning software and hardware and nothing makes ...

Re: Converting Mini to CBD Chitu 3.1 board

Update: I have the board mounted in the chassis and all the stepper connections fit the new board perfectly. Hopefully the rotation is correct. The firmware for the new board is G-code. I still have to figure out how to modify and flash the firmware to the board. I powered the board up with an ATX p...

Caeser, what setting do you need?
Also what would be a good hot end for PLA?

Re: Up Mini Crashed & now Not being recognized by PC

Copied and pasted from the email I got from Tiertime
mainboard is $253, while the price of CPU is $385.
Their prices have gone down overall but still way out there.

Re: Converting Mini to CBD Chitu 3.1 board

Also I just completed a ramps/arduino setup on my Davinci printer and its dialed in quite well. If you want to send a gcode file I could try it on that machine.
