Ulicreatr 2X dual Extrusion upgrade problems

[Shane 3]

My 2+ Extended keeps shutting down at the end of the bed preheat right before it preheats the nozzle before a print.

After the shut down it immediately restarts.

If I try to print a again, after restart, it shuts down about 1/2 way through the bed preheat. Sooner than before.

Theres no shutdown during manual preheat for bed and nozzle individually.

If I slice with the heated bed turned off I don't get a shutdown but still cant print because feeder 1 is inverted.

If I revert back to default firmware and unplug the kit hardware and plug in the original nozzle the machine works.

The nozzle heater blocks on this kit have 2 heating elements each and theres also an additional fan and heatsink on the print head.

I think the firmware is leapfrog.

This kit appears to consume more power than the original equipment.

Is this a power issue or maybe firmware settings.

I'm reaching out to the community for help on this matter because my machine has been down for about three weaks.

Perhaps Creatr support team is preoccupied with other projects. I don't know.

Can anybody Help.

They made it so it can only work with the bed off since it uses 80W heaters.

Also that means now that I think of it, that it quite sucks (sorry creatr) if you try to print with one nozzle... Wow didn't occur to me until now.

Max power for 1 heating element + bed I think it's around 50W (without changing the power brick). I have a 280W powersupply that I used when trying to make a dualhotend system and with that I was able to heat x2 40W hotends. So, I don't see how creatr it's going to allow 1 print nozzle + bed without more mods or changing the heaters...

Are you sure their 80W. 80w divided by 24 volts is 3.333333Amps.

I used a fluke 374 clamp meter in min/max mode to check current on the bed(6.5amps), LED's(0.3amps),dual cooling fans on the head(0.3amps)(I don't mean the 2 material cooling fans).one heating element of the hot end(1.7amps). If those blocks are 80w that over 10 amps. just for those 4 items. And that's not everthing at work. I didn't want to cut the cord on the expensive stock power source to check the overall current draw.

Sincerely I can't know for sure but Creatr guy sent (sam bianchi) a pm and when we did talk by email he said 70W heater cartridges.

Sorry I thought was 80W. But his mail says 70W

That's still to much current for my power source. gr5 said that the mother board pathways are identical for the hot end and heated bed. The bed is listed at 7.5amps so I'm guessing the hot end board path can handle the same. Does the marlin firmware require power source specifics. I looked on e-bay and there's plenty of options for under$100.00. 24v 12,13,14 and even 15 amp. Just need to add cords. So this would work. I just don't know much about the information the firmware requires to add this type of power source.

Sorry that I don't know. I used the 280W meanwell (to use the same brand as the original) without firmware changes but I was using 40W heaters...
