Re: 12v switching power source cannot go below 21.2v. - 10 years ago

Did you put any load on it ? Switching power supplies tend to have the output voltage 'float' if there is no current drawn, because they need some load for the reference voltage. If you want to draw say 10mA at 24V to check you just hook up a ~2400Ohm-ish resistor.

Ok, that's good, I was expecting infrared would not work on glass. That's definitely the sensor I want to use for bed levelling then. Do you also use a sunhokey ? Which mount did you use for the sensor ?

Quotetjnamtiw QuotefDutchman This is now on the Aliexpress home page: From now on, all orders that were placed after June 25th will receive an extra Buyer Protection time of 15 days after order completion! So it looks like there is hope for those who fell for the 15$ offer! Nope, just spent 'quality time' with a Chinaman posing as an American who told me that it only applies to orders completed

Re: Reinforcing acrylic frame - 11 years ago

Cool, I'll definitely join the owners group on thingiverse, already seen some other things I want do modify -auto bed leveling looks like a very handy thing to have. Do you still heat the plate with the glass on top ? I think I have some larger heatsinks somewhere in the house will have to try if they fit the driver boards.. Can't put anything too big on there I guess, especially since they a

Re: Reinforcing acrylic frame - 11 years ago

Yes, I'm in the Netherlands, I was expecting around €60 (48VAT+12 for FedEx), so it's good to see that figure confirmed. Is there a glass plate included in the kit ? I guess that will put off the heat measurement quite a bit with the PTC on the aluminum plate, or don't you need to heat the bed for PLA ? I read some people are using the cheap 22x22cm IKEA mirrors for the bed (they are very thin),

Re: Reinforcing acrylic frame - 11 years ago

Thanks, I went for a Prusa i3 because it seems to be the most used for DIY builds and there is lots of information on building and troubleshooting them. The sunhokey gets good reviews and many people get it running pretty decent (which at this price point is probably as good as it gets..) I looked into building one from a BOM, but there are so many possible variations it dazzled me. I decided to

No the seller is not mentioned, only my ordernumber. The seller was: Shenzhen Co.,Ltd They took the whole store down, that store URL now points to a non-existant page.. But the name and the storenumber (1936246) should help you put in a claim.

Re: Reinforcing acrylic frame - 11 years ago

Thanks for your elaborate reply! I have seen the build by Hiboson, excellent instructions, will be very helpful to get all parts mounted the right way. The fact that sunhokey takes the trouble to make improvements to their design for 2015 was one of the reasons I decided to purchase one. It shows they want to deliver a good product instead of a lot of similar kits that don't evolve after it 'sor

Re: Reinforcing acrylic frame - 11 years ago

Thanks for the heads up, there is also a thread about this too good to be true deal on the forum. Maybe I'll be testing the Alixperess buyer protection instead of starting a build..

Re: This offer sounds too good to be true - 11 years ago

I choose DHL as well and got a China post tracking number ending in 2952CN, not visible on the tracking site either. Looks like it may be fake and when you start a dispute to get the 15$ off (I got that offer as well) they complete the transaction and take your cash. If they can do that then this is a giant big loophole in the Aliexpress buyer protection!

Reinforcing acrylic frame - 11 years ago

Hi all, I purchased a Sunhokey, at least I hope so, because it was REALLY cheap I was already looking at different cheap 3D printers with acrylic frames and wondering about ways to make the frame more sturdy. I intend to bolt the printer down on a piece of plywood, so the base cannot warp and it will be easier to move without the need of recalibrating. Perhaps screw handles to the plywood so it

Re: This offer sounds too good to be true - 11 years ago

I stumbled over the same site on Sunday, ordered the sunhokey. Hoping that it's not a scam and the buyer protection works. I also received notice it got shipped today. Can't wait to see what will be delivered
