Is it just me ? I recently finished building my Delta and can honestly say I've had more headaches then enjoyment out of it so far, first the calibration was a pain, then the extruder wasn't putting enough filament to the hotend, now that I can actually print something at a very reduced speed due to bad extruder setup (waiting for a new setup), now my part is delaminating like crazy, I'm almost ready to throw in the towel, are others experiencing this too, or is it just me ? Also does PLA delaminate more than ABS ? https://reprap.org/forum/read.php?178,457208,457208#msg-457208 Mon, 16 Mar 2026 02:27:13 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?178,457208,458733#msg-458733 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,458733#msg-458733 Your thermister is either broken or one or both wires to the thermistor is broken (no connection).]]> rhmorrison Delta Machines Thu, 22 Jan 2015 02:57:26 -0500 https://reprap.org/forum/read.php?178,457208,458668#msg-458668 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,458668#msg-458668

I have a [SINTRON] 3D Printer full complete Kit for Reprap Prusa i3 ,MK3 heatbed,LCD,MK8
the temp reads 499 all the time.
I metered it and I get no reading at all.

d3delta3d, dougal1957 - thanks for the clarification, I also have a smoothieboard waiting in the wings for another 3d printer project or I may put it into the current delta I am running with a Rambo board.

vreihen - Yeah, it's an IR gun, they really are useless for pinpoint temp readings, I wonder if there is a better way to verify actual hotend temperatures without relying solely on the thermistor.

You can get multimeters that have a thermocouple measurement probe for Temps such as Fluke 87 multimeter this wont be the cheapest device out there but should give you some idea.

Where in the World are you based it may help someone give you better advise on what is available in your country

ie in the uk This one is cheap enough

I'm using a temp gun on the hot end and it's not even close to what I'm thinking it should be, are temp guns an accurate way of reading the hot end temps?

If you are referring to one of the non-contact IR guns with the laser pointer, the answer is no. They measure the temperature average over a large area, even up close. Mine also wouldn't even get close to the thermistor reading.....]]> vreihen Delta Machines Tue, 20 Jan 2015 06:52:32 -0500 https://reprap.org/forum/read.php?178,457208,457765#msg-457765 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457765#msg-457765

Hi . My post was a little unclear. Some firmware will have the most popular thermistor types programmed into the them like EPCOS100K or HONNEYWELL100K and luckily mine did. These will load in the Beta Value(K) of the thermocouple automatically. Because I purchased a unbranded Thermistor the company selling it included the beta Value (K) value in the description which for mine was 3974. This meant that for my firmware I added the line temperature_control.hotend.beta 3974 which lets firmware the know how to read the resistance of my thermistor to report the correct temperature. This is how Smoothieboard deals with them, and Marlin is a little different but this post might help.

This is true with Smoothieware but is totally different in Marlin where each type of thermistor is given a number and that is what needs to be defined to do this you really need to know what you have or replace it with a known one such as a semitec s104 (I think that's the one) these are what is used in a original E3D hotend and are number 5 in the Marlin config.

A lot of the Chinese one seem to have a beta value of 3950 and I don't think there is one in the Marlin table that matches that but I could be wrong as I use Repetier firmware.

HTH

Thanks for your input I really appreciate all the information I can get,
I'm not sure what you mean by the K number in firmware and why you changed the number, I'm using Marlin.

That's a nice looking extruder in the link.]]> jmf Delta Machines Mon, 19 Jan 2015 22:19:30 -0500 https://reprap.org/forum/read.php?178,457208,457687#msg-457687 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457687#msg-457687
I also found the K value in the firmware was set at a default to 4022 which suits most 100k thermistors and I had forgotten to change the value to 3974.

I am using a 5:1 reduction extruder from Infill 3D found here I have run it very fast with no problems]]> d3delta3d Delta Machines Mon, 19 Jan 2015 21:27:25 -0500 https://reprap.org/forum/read.php?178,457208,457683#msg-457683 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457683#msg-457683
That's what I'm beginning to think, I'm checking config right now.

I'm using a temp gun on the hot end and it's not even close to what I'm thinking it should be, are temp guns an accurate way of reading the hot end temps?

I increased to 220c and it seems much better, I'll keep experimenting a bit, the extruder wasn't working as hard either.]]> jmf Delta Machines Mon, 19 Jan 2015 21:05:32 -0500 https://reprap.org/forum/read.php?178,457208,457300#msg-457300 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457300#msg-457300 dc42 Delta Machines Mon, 19 Jan 2015 03:44:51 -0500 https://reprap.org/forum/read.php?178,457208,457275#msg-457275 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457275#msg-457275

I get delamination in PLA on both of my printers below 225 degrees
In fact, my best bonding and accuratesse is between 235 end 240

Thanks, I'll give the higher temps a try..

I think that it's just you. Everyone else's printers here went together without a hitch, and mine didn't even need calibration! :)

Seriously though, we all get frustrated at times, and most of us probably have a pile of printer parts that didn't work out for one reason or another. Take a step back, take a break, and look at every problem with a fresh perspective as they pop up.....

LOL, thanks !

At least I am seeing some progress.]]> jmf Delta Machines Sun, 18 Jan 2015 20:33:54 -0500 https://reprap.org/forum/read.php?178,457208,457230#msg-457230 Re: Is it just me ? https://reprap.org/forum/read.php?178,457208,457230#msg-457230
