General Discussion / Re: ABS without a hot bed
« on: February 24, 2017, 04:13:42 PM »
There are times that I think 3D printing is an art. The exact setup changes with what filament you use and what surface you are printing on, there is no check list that you can follow to get good results every time. The more time you spend refining the process the better the results, and the knowledge to tweak things when the results are not exactly what you want/expect.

When I got my first printer not knowing the difference I ordered ABS to learn printing with. Well today I get far better results with ABS than I do with PLA. I can get good results with PLA but its much easier to get what I want with ABS because I have worked with it so muck. Two of my 3 printers do have full enclosures and high power bed heaters.

I guess that I am the odd one because I use separate switches of X & Y homing.
On my L6 and CNC Shield there are headers so I can just plug the switches onto the boards without any soldering (I use the switches form the 3D printers).

well that is convenient.  My problem is i didnt want to wait a month for bangood.  I knew amazon would get them to me asap.  Havent heard of Folgertech.  I'll have to check them out
Folger's sell 3D printer kits, but I have found them to be a great place for a lot of the things you need for building cheap. Being so close there have been times when I got my order in early in the morning and had it delivered the next day. When they are real busy it can take a couple of days to get shipped.

There have been a few times when I wanted something that was not on the web but I knew they had so I called and they sold me what I wanted. One time I wanted aluminum plates and they said they were short but had some discolored ones that they gave me because they couldn't use them in their kits.

I had a similar break.

I ordered these: https://www.amazon.com/gp/product/B01G2WMRLE/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

They work perfect except they are reverse from the gearbest stock ones I had.  Ie plug in new cable and the motor runs in reverse.  Its fine.  T2 has a switch for that.

Pricey -- I can get them from Folger's for $1.99 in 300mm, 1000mm, or 2000mm
https://folgertech.com/products/motor-wire

And I can get the motor with the wire for $9.99.

I was just thinking that I need some more 20x40 rails and a 24V power supply so I can just add a bunch of the motor wires onto the order. I live less than 30 miles from them so I can get next day USPS delivery real cheap.

For me they are not quite long enough - first thing I did when I got the cutter was put new rails on it and its 600mm x 900mm. But they are long enough in a pinch, just start in the middle of the bed with small jobs.

And thanks for the link.

T2 Engraving / Re: using tiral version and getting engraving errors
« on: February 22, 2017, 03:33:20 PM »
Looking at the image it looks like it stopped etching before it finished.
Did you get an error message on the computer? When the demo software stops it will tell you that its stopping and why or there could have been an error sent from the GBRL firmware.

Also post the file that you were trying to etch so others can make sure there is nothing wrong with the image.

That happened to me the other day. I bought some nice coasters to etch. So I set things up and made a burn on cardboard to make sure everything was set up correctly and it was perfect. Started the coaster burn and watched for a few minutes, then went into the next room to get something and when I came back the job had stopped error/abort.

So I did a second burn that came out perfect on cardboard so I started another coaster. Watched for a little while and all was going well so I started doing something else in the room and a little later noticed that it had stopped again error/abort.

So I burnt a third cardboard perfect and started a third coaster and this time stayed watching. That is when I noticed it had a lot of flex in the X axis motor cable as it stopped.

On close inspection one of the wires had broken at the plug that goes into the motor, some of the time making good contact and sometimes not. Most have made a glitch that the GRBL firmware could detect and send an error.

After I fixed the motor wire went to the shop and sanded all of the coaster images out and went back and got perfect coasters. I think Murphy liked cardboard that day but not coasters or me. I need to order some extra motor cables just to have them for next time.

I think your flowery initials is not going to be a five minute task. I was going to demo laser etching last weekend at the model engineering show in Waltham Mass (was sick and did not attend)....

OFF TOPIC -
Do you live near Waltham? I live about 20 miles from there off Rt 2.
If so then I'm starting to understand how you think.

For slicing I like the Pursa 3D MK2 version of Slic3r. It comes as part of the Pursa i3 MK2 software package. I don't have the printer just the software, and It has some nice additions.

You can replace the MOSFET on the RAMPS board, I have a pile of parts but just have not gotten around to making the fix yet.

The best way to test is have the RAMPS board ask for heat from the hotbed and use a volt meter to measure to see if you are getting any voltage on the connector.

For where its located, if you look at the edge of the RAMPS board you will see the connector for D8, D8, D10 and just behind the connector are 3 MOSFETS with 2 in line with the length of the board and 1 sideways near D8, the one near D8 is the one for the bad.

Attached is a picture with the MOSFET removed - that is for the bed.

I have the FolgerTech i3 Prusa...while they are a US company, I'm sure they buy their kits from China. I've had it about a year now and it has worked perfectly until last week when my hot bed stopped getting hot. I have to still trouble shoot what is wrong and fix it. Probably a loose wire although I think I did a good solder job when attaching the wires. Maybe the hot bed went bad in which case I'll just buy a new one.

https://folgertech.com/products/folger-tech-reprap-prusa-i3-clear-frame-full-3d-printer-kit-ramps-gt2

Folger makes the kit themself, but most of the parts do come from China.
For the heated bed the most often point of failure is the MOSFET. I have 3 RAMPS boards with smoked MOSFET's. The 4th one I use to drive a relay that takes the load for the hotbed so I would not smoke another MOSFET.

I have some 6" medium tack transfer tape I use for vinyl graphics/stickers.
Will this work? I may try some it comes in lots of different widths
I don't have that material so I have never tried it, but give it a try and show us how it works.

Thanks. Where did you get the ecentrics?
This is where my supply comes from http://openbuildspartstore.com/eccentric-spacer/

It's funny. The two printers I am looking at are the ones the Ralph and Zax have. I just want to treat this like a boxing match. "In this corner ....."

Or like 3D combat "FIGHT!" ;D
I can break the tie, I have 2 of the Folger 2020 i3's, one all original and one with so many mod's there is almost nothing other than the frame that is original, and a Folger FT-5.
One thing about building a kit is you learn the details of how it works. Like the laser's things break and its good to know how to fix them.

exactly the Eccentric Spacers setups
They work very well, I have on on a 2080 beam for the Y axis on one of my i3's.
