Re: Wrong temperature
Andrew, i notice here at the board that RT2 refers to the extruder temperature ,so I change RT2 to 4.7 K. But now , bed temperature is about 10 degrees more than normal and extruder temperature is...
View ArticleRe: Wrong temperature
If you only changed one of the RT resistors, you'll need to combine the bed table from the 10K file and the extruder table from the 4k7 file. As for the extruder, did you adjust config.h to read the...

ok tnx Andrew ,i think now everything is working ok ,line 305 was wrong ,now it is correct. And for the bed, do you thing it would be better to change RT1 to 4.7 K ?
View ArticleRe: Wrong temperature
You'd get better resolution at high temperatures, but the 10K table you're using is good enough for bed control, so I wouldn't bother. The file I included last post has a bed table for a 10K sense...

I have been thinking of maybe creating a fan-cover that distributes air to two different areas, most of the air goes to cooling the top of the hotend and the extruder, and a small portion is...

View Article12V PSU connection, using only one V0
Hi, I've currently ordered a printer from MixShop and the PSU isn't working well. One V0 isn't working, and one is working fine. I've got two sets of V0 / V12. Can I plug two cables on the same V0...
View ArticleRe: 12V PSU connection, using only one V0
all ground (0v) will be connected to the same point in the psu. It will be fine to use a different one
View ArticleRe: 12V PSU connection, using only one V0
Actually, I've made a mistake. Both V0 were working fine, it is one V12 that isn't working. Would wiring both wires through a single V12 damage the PSU?
View ArticleRe: 12V PSU connection, using only one V0
it depends on the psu. technically it should shut down if you draw too much current but there are a lot of supplies out there that dont do what they should. what does the sticker on your psu say about...
