Welcome to the SeeMeCNC Community

You could have reduced the layer height to .2mm and halved the time. It's really not such a big deal to leave these printers going for hundreds of hours. You just have to be confident in your gcode.

If you had previously halved the steps/mm, then it would print well with 8 set. Each time you change the microstepping, you need reduce (or increase) the steps/mm.

I don't think you can just divide the steps/mm by 2. You have to change the microstepping for the motor driver in firmware. I believe there is a line in repetier that has the microstepping factors set in an array (16 16 16 16 16) I would assume it goes (X Y Z E0 E1) But I'm not positive.

I wouldn't do it in bridge (never tried it, can it withstand such huge parts without warping?) but I would do it in PLA in a heartbeat. Put it at an angle and put supports on the underside and anywhere that is an "island" It would print really nicely. I do lots of pieces like it. First tim...

Definitely, smaller filament works well with it. But as stated, filament tends to hover around 1.8 or above too often for this to be reliable. Also, I never saw any added benefit to the 1.8. Performance seemed the same as a 2.0mm one.

I'm glad I could help. Saving someone the wasted time is why I like updating threads. Just as a note, going to the 2.0mm tube from the 1.8mm alleviated all the problems I was having in this post. I can now print with the .25mm nozzle, at 50 mm/s running my usual retraction settings. Bad 1.8mm bowden...

The question seems to have been posed about dc42 fw, the dc42 branch of RepRapFirmware, running on smoothieboards. The calibration system alone is only a small part of the dc42 fw.

Yup, totally. I just saw this tube available and thought "hey maybe that will help reduce bowden effects." I saw no reduction, at all, of the negative effects of a bowden system, and only added drawback. Just wanted to update everyone in the thread to not follow in the 1.8mm ID footsteps.

It wouldn't unless it was ported. I heard 626pilot may be thinking of doing just that (for the motion portion).

So it seems that moving to a 2.0mm ID bowden tube actually improves the performance over the 1.8mm ID tube. If there is a benefit to be seen by the 1.8mm ID, it is not in long bowden tubes. Perhaps if the system is direct drive but requires a bit of ptfe tube, the 1.8mm might be a nicer choice... bu...

Automated hydraulic presses? CNC routers? WTF? I can definitely see the overthinking. Berry werner has a video where he shows the jig he uses to make his arms.

Right, I forgot that the tape includes multiple sheets. I do agree that you can save some money with the thin sheet, but it seems like an insignificant amount of money to me. Maybe I just don't value money as much as I should. I do order from Amazon, their ultem 1000 12"x12". The sheets I'...

My tips for using buildtak: put it in the garbage. A giant time and money waste. PEI is the answer you were hoping for.

I'd like to chime in, as I'm one who has used 1/8" without adhesive. There is no noticeable increase in heat-up time. With a sufficient power supply and insulation under the bed, the heat up times are FAR better than a stock rostock max. The flatness of the sheet after being clamped is better t...

Yeah, kinda "ad-y" but since it's open source, we should let it slide. They're sharing info for free. One of the huge hurdles of our economy is the hoarding of information -- anyone willing to share it gets a pass in my book.

I really don't like this attitude that s3d is dumb to do this. Who are you to tell us what is and isn't dumb? What if I wanted to make a microscale fdm printer? Why should I not be allowed to? Because some firmware devs think so? Sorry, but the insane detail from s3d gcode does amazing things with t...

Is that with the 300 MM Carbon Fiber Tube Arms ? or same for all? Delta radius is independent of arm length, that's why you can adjust them individually. This is very true. I was surprised to discover this. In my CAD assembly of my delta, changing the arms does nothing to the HR -- it stays precise...

Here's the motor that I'm going with for a similar setup: http://www.omc-stepperonline.com/gear-ratio-271-planetary-gearbox-dual-shaft-nema-11-stepper-11hs120674d1pg27-p-263.html" onclick="window.open(this.href);return false; It's also a 27:1 geared Nema 11, 120 grams, and only $32. Cavea...

This all goes back to that idea of a counter-weight. I believe werner berry does this. Replace that center column with a rope and pulley with a counter-weight on the other end, to allow the extruders to float. No added electronics, very simple and cheap mechanics.

If you're talking about ABS, I have the best luck going to like 100 minimum. 110 or 115 sometimes, even.

Thew fewer letters in the URL, and the less ambiguous, the better.

MH3D.blogspot.com sounds good. Alas, it's taken. Eaglezsoar's suggestion was good. Use your name recognition. mhackney.blogspot.com ...also taken... hrmm

So then, what are good URLs that are available on the platform of your choice? This will allow you to filter out any names that are already taken.

If you are looking to host it yourself, with a domain name of your choice, I would go by what domain names are available.

Love that test rig. I'm going to be mounting a new extruder system onto my effector soon so I will have to use that to calibrate it.
