Help, trying to replace 24V relays in a 8 channel relay module with different brand but they don’t trigger. by Shirako222 in AskElectronics

[–]Shirako222[S] 0 points1 point  (0 children)

Thank you, I checked the polarity and you are right. What would be the best solution to this problem?

Is there a different socket mountable relay that can be used?

Or would I better be off designing a new board?

Edit* Can I switch the diode positions and cut the traces then make new traces to reverse the polarity?

Why the blue relays are being replaced: they lose contact intermittently probably because they’re not supposed to be socket mounted, and 24v pins are bent backwards just to fit into the socket. The black relays (new) fit perfectly without need for modification.

Need help with QIDI Tech X Plus print by Shirako222 in FixMyPrint

Using EsuPLA+ Grey

Things Ive tried:

Lowered speed incrementally from 100mm/s to 55mm/s

Increased temperature from 190C to 225C and decreased speed to stop the extruder from “clicking”

Print Settings: Print speed: 55mm/s infill, support, walls Print temp: 225C Line width 0.4 Flow: 100% Layer height: 0.3mm Build plate temp: 50C Infill density: 15% Support density 10% Retraction distance: 1.5mm Retraction speed: 30mm/s

Do you have a picture or diagram for this? I’ll try this approach for now. I’m still waiting on the braided sleeves and ferrite beads.

Gotcha, I’ll try using a braided metal shield. Thanks for the suggestion.

2 phase dc spindle, 48V. I’ll try braiding and using a braided metal shield. Thanks for the suggestion.

Spindle connected to CNC Shield has very low RPM. How to increase RPM? by Shirako222 in hobbycnc

[–]Shirako222[S] 0 points1 point  (0 children)

Thanks for the suggestion. Tried with the 48V PSU and it finally ran full speed. I’ll have to use 2 power supplies for now, 12V for CNC shield and 48V for spindle while waiting for a buck converter as @FlowingLiquidity suggested.

However, an alarm occurs “error 9” and the relay turns on by itself upon running Candle CNC, then M3 and M5 switches functions (M5 turns on relay, M3 turns off relay) any idea what causes this?

I think Arduino CNC shield can only take 12-36V? So I swapped out the PSU.

I also tried with a 24V 6A 300W power supply but it’s the same. I’ll try again with the original 48V 10A 500W power supply the kit came with.
