Wanhao Printer Owners

Hi,

Anyone know where I can get an extruder motor cable in the UK? For the duplicator i3 v1. I can't find one in the usual supplier websites.
Could it be the same as one of the other motor cables?

Trying to verify/adjust the driver current for the stepper motors. The printer has "Moons Stepping Motors". Found their website, but none of their stepper motor part numbers match the ones installed in the printer. Does anyone have information on the following motors: C17HD6039-06N or C17HD40102-01N?

I've been printing since Aug 2018 when I initially got the Monoprice Maker Select V2.1. I first upgraded the bed to a glass plate which helped things immensely but I'm a tinkerer and I couldn't let well enough alone. I kept upgrading things. Next was a DiiiCooler which again was a fantastic upgrade. I decided to print a Z-Brace which went fine and at that point I figured since I had the whole thing apart I would upgrade the extruder lever and hot end with the Micro Swiss all metal versions. Up to this point, everything was fine.

When I went to put everything back together though I had a big problem: One of the wires on the heat cartridge snapped. I read around and saw that it was a relatively easy fix so I found a heat cartridge online and ordered it. I was stupid, though, and I got a 6mm cartridge instead of the 6.3mm one. After trying to make it work I gave in and ordered the 6.3mm ones. They finally came and now I've gotten one installed but now it will only hit 200C if I don't have any kind of thermal protection on the hot end. With thermal protection it peters out around 175-180C.

I'm still so new to all this...wiring included and I assume I've done something entirely stupid that has either ruined everything or is very easy to fix but I can't figure it out. So, I'm putting it out there. I'll do my best to answer any follow-up questions but I'm putting up the white flag.

Here are the parts I've changed:

All Metal Hotend - https://www.amazon.com/gp/product/B01E1HANLS/ref=ppx_yo_dt_b_asin_title_o07__o00_s01?ie=UTF8&psc=1
Extruder Lever/Plate - https://www.amazon.com/gp/product/B06WVB6CYD/ref=ppx_yo_dt_b_asin_title_o08__o00_s02?ie=UTF8&psc=1

Update: I've double checked all the connections and this time instead of being fancy and trying to solder the new heater cartridge in I've attached it directly into the board. Still hitting the 180C-ish mark and petering out. I did do a test to see at what registered temp PLA is able to start flowing and the machine is registering around 175-178 before PLA will start to come through the nozzle which seems to be about right (depending on the quality of material which since I just grabbed the filament that came with the printer originally I'm guessing was low).

I am currently trying to run a PID auto-tune which I think is going to be a bust since with both the hot end fan and extruder fan running the thing is struggling to even hit 100C.

RESOLVED:
Finally got the 12v heater cartridges in the mail today. Crimped connectors in just above the hot end and attached everything. Now its heating great. 1m35s to 200C and 1m58s to 230C. Super fast.

Hi all.
My wanhao I3 Plus Mk2 will not extrude after pause or power resume..x, y & z return to correct position, and "print " resumes, but extruder motor does not run for the rest of the layer...then begins extruding on the next layer, but of course it's a mess....anyone else have this issue....updated to the latest firmware, tried scripts in cura and machine pauses...all the same issue...really means I cannot change colours in a print....any advice would be greatly appreciated.

Hi all,

I've got a really odd issue, wondering if anyone has seen it before or knows what could be causing it.
My i3 will not extrude on the left side of the bed but is perfectly fine on the right side. This isn't related to bed levelling because if I raise the Z axis up away from the bed, heat the hot end and move the extruder position so it extrudes filament, it works fine on the far right. If I move the X over to the left, from about the centre of the bed to the far left it won't extrude.
Can't for the life of me figure out what could be causing it.

Any guesses??

Cheers
