Demonstration of a Flashforge Dreamer with TMC2208 based driver boards installed on the X and Y axis.
EDIT (03-18-2019):
I did not need to make any changes to the firmware or Flashprint to use this modification. My driver board was not plug and play because most TMC2208 drivers have the pins soldered on the side opposite of the drivers on the Flashforge Dreamer. I removed all the pins and installed new ones on the correct side. An easier method would be to purchase boards without preinstalled pins, then install them on the correct side yourself. Finally, the polarity of the stepper motors with upgraded drivers need to be reversed to compensate for the reversed polarity on the TMC drivers.
EDIT (04-11-2020):
I have recently upgraded the driver board for the Z axis as well, and found that there is sufficient torque for flawless performance, even without spreadcycle mode enabled.
Summary:
1. Plug and play in terms of software/firmware
2. Not plug and play in terms of hardware
(a) orient driver pins correctly
(b) correct polarity on stepper motors
These are the specific drivers boards I used:

I convert my Dreamer to IDEX System. Work perfect

@bobbykoulouris 3 года назад

man, I totally appreciate this video! I bought some TMC2208s and after watching a few videos i was discouraged that I woudnt be able to use these on my (Dreamer Clone) Powerspec Ultra and it worked so well. Did you need to adjust the pot one the drivers or did you leave them as is? Thanks again. I converted X Y and Z

@aphex4000 3 года назад

Glad you found this video useful. I checked the reference voltages and they were all correct so I did not adjust the pots.

@farfarakabo6007 3 года назад

what voltage are you running your drivers at, for this setup?

@aphex4000 3 года назад

Hi, assuming you are talking about the reference voltages, they have all been left at 1.

@phil.tsao. 4 года назад

This is great, thanks for sharing. From what I've read it seems like the TMC2208 by default is in 1/16 Stealthchop mode. Apparently Stealthchop mode has less torque and can lead to skipped steps but is way quieter than Spreadcycle, which you had to configure through UART. Have you had any issues of skipped steps? I'm about the do the same upgrade myself.

@aphex4000 4 года назад

I have not had any issues with skipped steps, but shared your concern in the beginning as well. I recently upgraded the driver for the Z-axis as well and have not encountered any problems there either.

@phil.tsao. 4 года назад

@@aphex4000 awesome that's great to hear 🙂 I'm planning to just upgrade the X and Y since those are the main contributors to noise. I guess I'll just leave them in stealthchop! Thanks!

@phil.tsao. 4 года назад

I made this change yesterday and holy crap it made such a huge difference in terms of noise! Amazing. Thanks for your help & instructions!

@@phil.tsao. Hi Philip, Did you noticed any printing problems? I had all sorts of problems, from skipping steps, horrible printing quality and random printing errors

@GeoffreyHart_ClementsHS 5 лет назад

So the drivers needed to be flipped and repinned and the polarity of motors needed to be flipped. Does this just mean swapping the voltage (red) and ground (black) pins on the jst jack where the motor gets plugged into the board? It doesn't sound too bad. Did you have to change any vrefs on the drivers or anything like that or was it just plug and go? I know it's a long shot but any chance you could post pictures or a video of what your board looks like now? Thanks for the video and info!

@aphex4000 5 лет назад

1. Yes, for the specific drivers that I used the pins needed to be flipped. 2. On my board, the wires I flipped were red and yellow (not black) 3. I only verified that the vrefs came pre-set from the factory at 1, and made no adjustment. 4. Here is a photo of the board in its current configuration: photos.app.goo.gl/QN2XMABtpm79Ee6e8 * Here is a link to a video of the upgraded fan bracket being printed with the new drivers installed: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QR-POBpWKu0.html

Does anyone know what the V.ref voltages should be set to? Thanks

@aphex4000 2 года назад

Hey Danny, I have the reference voltage for all three boards set to 1.

@HronoLab 3 года назад

Great job! I have a question about motor wires. You sad that it should be reversed. Can you show a comparison picture of motor wires before and after installation? For example I have red/yellow/blue/green with my stock driver. Do i need to change it to green/blue/yellow/red?

@HronoLab 3 года назад

Also what is the firmware version on your printer?

@aphex4000 3 года назад

Thanks! You only need to swap the red and yellow wire of the wire for each driver replaced. Photo link in updated video description. I am currently running the [ v2.14 20191123 ] firmware.

@mcmariHD 5 лет назад

Is it plug and play to change the drivers or do I have to adapt the software? Can the change also be made for the Z-axis? How many drivers do I need to make such a change? I also own a dreamer. Thanks for the video.

@aphex4000 5 лет назад

I did not need to make any changes to the firmware or Flashprint to use this modification. My driver board was not plug and play because most TMC2208 drivers have the pins soldered on the side opposite of the drivers on the Flashforge Dreamer. I removed all the pins and installed new ones on the correct side. An easier method would be to purchase boards without preinstalled pins, then install them on the correct side yourself. Finally, the polarity of the stepper motors with upgraded drivers need to be reversed to compensate for the reversed polarity on the TMC drivers. The Z axis driver can be changed as well, but I would recommend switching the drivers to Spreadcycle mode for the increased torque needed to move the platform. There are additionally two drivers for the extruder motors, but I did not see the need to change them since they produce no perceivable noise and would not benefit from microstepping. All things considered, two drivers (X and Y axis) appear to be sufficient to gain the maximum benefit from this upgrade. Summary: 1. Plug and play in terms of software/firmware 2. Not plug and play in terms of hardware (a) orient driver pins correctly (b) correct polarity on stepper motors)

Sorry, no. I have only tried the TMC 2208

@TheCapitaotmn 4 года назад

@aphex4000 Hi, First of all, thank you for your instructions on how to change the drivers. I own a FF Dreamer and I replaced the X and Y drivers, but I wanted to replace also the Z. Bought the exact same drivers as you have used, but I cannot find any info on how to change the driver to spreadcycle as you suggested. Can you help? Thanks in advance.

@aphex4000 4 года назад

Hi Cap TMN, I did get around to changing the driver board for my FF Dreamer and found that there is sufficient torque to drive the axis and spreadcycle mode is not needed. I'll update the video notes to reflect this.

@@aphex4000 Hi, after a lot of awful prints, hot end alignment and changes, I have now reverted back to the factory drivers. Don't know what happened but cannot get a proper printing with the tmc's... bridging is impossible and horrible and I get all sorts of random printing failures/defects. Tried all kinds of tweaks in the settings without any good results. Been testing and reverting back changes up to the drivers. Just printed one of my last prints after the driver change and it's day and night. Any ideas? I'm missing the 2208's silence already but prefer to have usable prints

@aphex4000 4 года назад

@@TheCapitaotmn No alignment or hot end changes should need to be made as part of this upgrade. The only things that needed to be touched are the boards and stepper motor wires. Are you able to print temperature tower/bridging tests without any issues using the original drivers, but cannot as soon as you switch to the 2208's?

@TheCapitaotmn 4 года назад

@@aphex4000 Hi, Thanks for your quick answer. I had a lot of issues around the time that I changed the drivers, but just before I had also changed the extruders to all metal. I cannot do a proper print, not perfect, not even average. Temp tower was miserable and bridging was non existent. After having enough, started undoing the mods. Installed and align original extruders and tested, same... changed drivers and printed very reasonably straight away. Cannot understand why, really. I was loving the silence, but all prints were a hit and miss. I couldn't 2 prints with the same g code that would be exactly the same. Always different errors on the prints. Example: next pic is after changing back to older drivers (same g code and filament) i.postimg.cc/W1j7yvGm/20200717-174303.jpg Example with 2208's i.postimg.cc/bwsvpG9q/20200717-174308.jpg

hello i would be curious that for the tmc controllers where the uart has a leg i have to do something with it just because there is no ms3 as jumper on the motherboard
