Larger print volume and heated enclosure

I modified my M2 about 6 years ago to have a 12.17" x 9.75 build area with a closed-loop feedback build volume. I think the z height is increased too. I got this almost to the finish line then ran out of gas. I tested it using a hairdryer for a heat source and it worked except the Y-axis was missing...

Re: How to home to a level below the z limit switch?

Thanks for the feedback, guys. The Makergear forum group is one of the best I've seen.

How to home to a level below the z limit switch?

I have an actuator on my printer that flips the z home switch down using the x axis movement. The nozzle is about 7mm lower than the trip point of the z home switch. I've tried a bunch of script commands in simplify 3D to try to set the z offset 7.9 mm below the position where the home switch trippe...

Re: Software to include with the M2?

The biggest problem I had when I first started with the Lulzbot TAZ was figuring out how to install Pronterface and Sli3er and getting the initial settings in Sli3er correct. IMO, they could have saved everyone a LOT of headaches by just doing the following: 1. Include a DVD that walks you through t...

Re: Converting the 12VDC M2 bed heater to work with 24VDC

I = V/R so higher ohms means lower current means slower heating. You have to make sure that your power supply can handle whatever resistance you connect it to.

Re: Need help with Curtis's Firmware that supports VIKI

Maybe a wiring issue, as you said above? Did you try checking wire continuity on all the wires you can reach? I checked the wires and made sure everything was plugged in correctly. It worked for a while then started blinking again. I didn't change or even move anything and when I turned it on tonig...

Re: My enclosure

I had to order a FDM part made from Ultem 9085 today. It has a glass transition temp of 186C. That's probably where Jin saw temps that high for Stratasys machines. I think an enclosure at any higher than ambient and steady temperature should help. Hopefully I'll be able to figure out a lot more deta...

Re: PLA curling up from bed

You can add tabs on the corners of your part model that are around 1/2" to 1" diameter and 5 layers thick. That will also help hold the corners down and you can easily trim them off when the part is finished. Some geometries are harder to hold down than others.

Re: My enclosure

Googling around, I find claims that Stratasys machines run their enclosures at 50C. I don't think you want to actually reach the glass transition temperature, and 50C should be suitable to reduce warping in large prints. I think Jim was the one who found that they run at 70-90C. Would you mind post...

Re: Need help with Curtis's Firmware that supports VIKI

When I unplugged the entire bottom connector of the VIKI the flashing stopped and everything is still controllable. I guess that means the bottom connector is related to the SD card?

I'll try plugging the bottom connector back in then unplugging EXT2 20 and see what happens.
