Re: How to set the fillamnt fan on a CTC printer

Could you look in your Tools/Firmware Configuration menu under the X3G tab and tell me which printer is selected there and your steps/mm for your axis?

Re: How to set the fillamnt fan on a CTC printer

Sure:
Primary Axis; X: 94,139704, Y: 94,139704, Z: 400,000000
Extruders; A: 96,2752018703, B: 96,2752018703

Re: How to set the fillamnt fan on a CTC printer

I added the major RGB circuit components. I forgot to print the schematic and bring it with me, so I haven't installed the resistors yet. Staple parts, so I have them. I'll get them on the next pass as well as the header.

It turned out that the original part I ordered fit just fine. Didn't need to order the VSSOP package. I didn't make a video, but I followed the same techniques in the youtube videos I posted. As mentioned, the hardest part was keeping the part still while trying to line it up. I skipped the glue part and paid for it in some frustration. lol

Parts added:
Q6 (Cooling fan FET)
U19 (Hex inverter for RGB circuit)
U15 (RGB LED driver)
U16,u17,u18 (RGB FETs)

Still need to add:
R110-R115
Header

Re: How to set the fillamnt fan on a CTC printer

cool

can you please post the part numbers you used and of the peaces still needed?

did my numbers help you setting up the printer?

That was my order from Mouser. You don't need the last item. That's the FET you already installed for the fan.

You need 1x PCA9533 and 1x 74HC3G14DC and 3x of the FDV301N FETs, but I ordered a few just in case I messed something up. You will also need 3x 100K resistors and 3x 1M resistors and a 4 pin header

The resistors appear to be 0603 packages (haven't confirmed)

24V RGB LED strips are not so common. You could find some 12V LEDs and change out the resistors. Just double whatever resistance they are to keep the same current.

I have attached the schematics and bill of materials for the mightyboard as well.

Re: How to set the fillamnt fan on a CTC printer

No. I learned that the numbers entered into the Simplify3D dialog are pretty much ignored except in jog mode. I had to create a custom gpx.ini and some other modifications within Simplify3D. I posted the details here: http://forum.simplify3d.com/viewtopic.php?f=8&t=1623. You might want to check it out and save it if you ever need to make adjustments.

Can some one tell me an exact part nr or model of this resisors that should be ordered from mouser.com .
I check on main board and I think they should be 1 mm long to fit on soldering pads but what kind of Power Rating they should have ?
