Looks good. Similar to the tiny thermal barrier I saw on prusa's i3 in NY. I was worried about strength a bit too, good pic to show the strength!

chriss33, because it is a large 15" square, usps is the cheapest shipping method, and it's $45 usd to the uk, or pretty mmuch anywehre outside the US, Canada and Mexico. If you're interested, let me know, our website doesn't calculate shipping it well, so I'll just send you a paypal invoice for it.

LOL, ok, you want the heatsink back in it? I can do that. Maybe paint them hot pink or red, so then they are like motor "accents", like a spoiler for the trunk of a FWD car. hahaha

We are offering a lasercut melamine/wood laminate version of the i3 Frame/Y table and misc. parts on our website now. The aluminum looks pretty nice, and is a tiny bit more rigid, but not by much, and certainly a lot more $$$$ We have also noticed a lot of people mixing up which hardware and where, so I thought if I just mark where they go, you can drill for whatever hardware you choose.

So I decided to add a lasercut laminate to our website tonight. It's the same melamine material that we're using in our rostockMAX kits, it's super strong and stiff, and super cheap! The only mods made to Joey's files are, I removed the heatsinks (since we're cutting wood not al) and also I am just spot marking where all the holes are supposed to be. I've seen a lot of people mixing up which

VDX, thanks, yes, I found a pdf of the exact synrad tube, and yep 5V signal running recommended 5khz signal with PWM for power. Next up is how to drive the "tickle pulse", a 2ms pulse, to ionize the tube just below firing so it can respond fast when rastering.
Got the X Y stages running this weekend, even fired up the tubes PS and tested it out. Seems it still works, so we're good there, no

Thought I'd share our fun little project we started this evening with you guys.
Here's some Pictures of the start of the project.
A friend has an old (circa 1994) Universal brand 50W laser that he used in his shop up until 2006, when the brains released the magical blue smoke. Problem was, he bought thier #2 prototype for that model, and they told him no luck with support or parts etc... for

Tmives, yes, anyone can/should be able to unless they've botched their firmware somehow? Try this instead
G4 S5.35
some
g
code
G4 S3.0
You can use P for milliseconds OR S for seconds, at least in Marlin/sprinter/repetier it works this way, not sure about others.
Try using the S (seconds) call for the dwell and report back your findings?

You guys seen the RAMBo board, from UltiMachine, creator of ramps? It has digipots for microstepping and current settings to all 5 on board drivers. It soumds like exactly what youre looking for, and firmware has the M codes to adjust it, on the fly, if wanted!

We are looking into doing 3/16" aluminum milled plates for the i3. After checking josefs out at NY, no way, they arent 16mm. Waterjetting is too expensive, but we have 4 mills, and some unique fixtures, so we can mill them. We are prob going to use a tool and jig plate aluminum, its much stiffer and flatter than standard 6160.

Yep, no problem. And yes, 3 do make sense for the bearings, but 4 eliminate any chances. I've ran 3 on the MAX acrylic machine for a while now with no issues. It could be that becuase we are using the carriage in a vertical orientation rather than horizontal that the binding doesn't happen?

Crispy, thanks for dxf's
1. I like to use 3 bearings, steve likes 4, so since we "agree to disagree" haha, we made them for either setup.
2. We used 1/4" acrylic in the machine you saw at NY, and the white melamine laserboard is .270" thick
3. Crispy, im positive that those files for the idler end and motor side should be in the main release zip on the rostock MAX wiki page,

The best part of the show hands down was talking to people, and learning more about the as

It was reallly great to get to meet in person with all you guys too. Ak and crispy, thanks for spending some time chatting, got some great ideas. Akhlut, i dig the prism 1.5. It was real good to talk to you about our goals as being the hardware guys that can help bring the designs to the masses. We def want to do more of that. Eric is drawing up some stuff in the back of the van as i type. Haha.

Hook the fan up to D9 i believe on the ramps shield. You can turn the fan on/off and measure voltage at the D9 connector and see if it is D9 or maybe it was D8? Not at a printer at the moment. Its one of the three connections.

Well, atepper motors dont really "strain" they skip. With the RAMPS board i was running them with normal current settings on the pots, slightly less actually, and with the RAMBo boards you assign a pwm to control the current, and Im running 185, whuch equals appx 1amp going into the motors, which are rated for more than that by far
