I just bit the bullet and purchased my first 3d printer last night, a FLSUN 3D METAL FRAME KOSSEL DELTA DIY KIT. However, I purchased a kit without a heating bed and PSU for the heating bed.
I’m just looking at the heating bed that I require and the recommendation is to go with a 12 V 16.5 A PSU according to the website to power the heating bed.
My question, is there any harm in going with a 12 V 20 A capable PSU instead of the 16.5A PSU? My understanding is that the heating bed should only pull a certain amount of current so if I have a PSU that can supply more, then that shouldn’t be a problem.
Thanks and looking forward to your feedback and trying 3D printing.
Welcome to the party. The kit should be relatively easy to put together, though calibration will be time consuming to get correct at first. Just hang in there. You might also consider visiting the delta page of the RepRap forums if you need any help.
As Marc mentioned, a larger amperage power supply will not be a problem. However, I recently picked up an aftermarket power brick for an XBox One (16.5ish amps) that I used to finally setup my heated bed from Ultibots. Believe it was only $10-15, lot better than the $40ish power supplies I have seen. Eventually need to add a switch to it though, and had to chop off the proprietary plug.
I’m in JHB if you’re up here you can come by and I’ll help you put it together. I can also put you in touch with the suppliers for bits and pieces you may end up looking for.
Another ZA here. Look for the book ‘3D printing with Delta printers’ by Charles Bell, published by APress. I waiting for delivery of my first printer as well (Trium by e-mergin), also a delta. Any day now.
