maximum print temperatures


Trying to print some more exotic materials, not super exotic, but E3D's PCA/ABS mix, the problem is that they recommend extruder temps around 270 degrees. According to web data, the HS should reach 275 degrees, mine never does, maximum on my printer is 265. Same goes for the heated bed, Lpfrg info says 50-95 degrees, correct numbers are 50-85. 

The material of choice is recommended to be printed with a 130 degree bed temp and I know this is a stretch, but the material where bought before knowing for certain bed temp for the HS, I just assumed the bed temp would be enough.

Generally pinting with ABS, I would like a higher bed temp, this to avoid warping. I have some parts, a bit bigger parts that are impossible to print using ABS on the HS. 

I've asked Lfrg concerning this issue, their response to the bed temp is that parts on the printer might begin to melt??, upon asking which parts, so far no answer from Lfrg. 

I'm a bit concerned, when I bought this printer, I found the temperatures to be a bit low to begin with, learning this, that now seems to be a fact, it kind of changes things. 

does anyone know if the temperatures are changeable via the frimware ? 

I'm willing to do this, knowing full well that any warranty will be void. I'm simply thinking about exchanging the heater bed for a aluminum one with a 230 v heater. 

Lpfrg surely has its reason for limiting these values, things that concerns me though are un-accurate information, it might not be by much, but enough to be a annoying fact. 

The silicone heater for the bed is not glued onto the hole surface, only the edges, the tempsensor and a some dots in the middle. I cut mine of the glass and  glued the whole surface with hight temp silicon glue and no air pockets.  120 deg, no problem,  20-100deg in 16min. Before the regluing 92 was the max reported temp on my bed , and mesuring with a thermo camera most parts of the bed printing area was < 50deg.


Ok, good tip, I will try this immediately. 


Do you perhaps know which glue you used ? 

Sorry I don't remember. I used a 1 component silicon that was marked with +250 °C (200-220 °C would be sufficient). I used app 300g but squeeeeezed out most of it to get rid of air bubbles and to get as thin layer as possible. Its rely important to have no bubbles. one bubble the size of a coin can damage the heater (PTC effect),bubbles all over the surface = no risk of damage but poor performance. It took 48h to cure the glue @ 45 °C.
I also glued thick aluminium foil on the bottom side of the heater then the insulation. This has no effect if the addition to the glass is perfect, but who knows if its perfect.....
Good luck!


Ok, thanks, 

Anders that's a great hack. Could you please provide pictures of what it looks like? This is certainly one of my biggest gripes with the HS

 I only had a pic of how the heater was glued from the beginning. If your heater is the same you see this when the air is expanding during heat-up. At 80-90 deg the airgap heater/glass is app 5mm in between the dots of glue and you can feel this clearly.

After a few moth of use, I think the PSU starts to overheat = the heating power goes down to 50% after a few minutes, this might also be a case of slowly heating bed, Cleaning the PSU from dust made some improvements but not back to 100% al the time, and I'm nor sure this was the problem.

Typical, before I even got started with this hack, my heater gave up. Found that the connector just underneath the bed had a faulty connection. The connector had apparently been exposed to some heat (due to connect error). 

Tried to fix the problem by exchanging the connectors, but the copper wire that runs to the bed had seen some oxidation, so any true connection wasn't possible, it seems. The bed in this state had a maximum temperature of 45 degrees. 

Re-tried by cleaning the copper wire and soldering new cables, better, but not near the original maximum temp 85 ° (which is a bit low to begin with ), now it only reaches 55°.

I believe my heater is defect, contacted lpfrg, it seems that the recognize this issue, as far as I can tell they will send me a new heater (warranty). 

Anyone had thoughts on fitting a 230v heater, seems like a somewhat simple solution. Alu bed, thermistor attached to the middle of the bed?

Would probably be easier on the PSU, easier to run higher wattage on the heater.

Quick Start Guide

Installation clips
The following 3 clips will guide you through the installation process of your Creatr. By following these, you will be printing within 30 minutes. First start with unpacking the printer. Clickhere to see how you correctly pick up the printer

Part 1 of 3: Unpacking your Creatr

In this clip, you will be guided through the unpacking of a brand new Creatr. The unboxing along with the location of tie wraps which need to be removed are shown, as well as the process of a connecting the cables to the printer and computer.

Part 2 of 3: Software and configuration

In this clip, we will show you how to install the required software. The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the Repetier Host Leapfrog software or that controlls your 3D printer. We have tried to make this as simple as possible and also provided direct downloading links per operating system.

If you are using the new Simplify 3D software you can follow all the steps except for the Repetier-Host Leapfrog installation and using explanation. Simply download the software via the purchase link and before first use a pop-up will appear showing you the Simplify 3D Quick start guide. You can also download the Quick start guide or access it from the software via help –> Quick start guide. The quick start guide will briefly explain the functions of the software so that you can start your first print.

Please select you operating system and follow the descriptions in the movie.

Operating systemWindows

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. The next step is to download and install the newest version of the Repetier Host Leapfrog software as shown in the clip. This software allows you to convert your 3D software file [STL for example] to a printable file [G-Code] and allows you to control your printer. The Repetier Host Leapfrog software contains standard Creatr Print Profiles. Just select the extruder, the filament material as well as the color and Repetier will automatically select the ideal print temperature providing you the best print quality possible. There is also a Leapfrog support button implemented in the software. A Mac version will be available soon.

If you have followed the installation procedure, but you can’t control your Leapfrog Creatr and the “6 commands waiting” message in Repetier-Host Leapfrog won’t disappear, you have to install the 2.8.28 drivers. Please see Solution can’t connect 6 commands waiting in Repetier-Host Leapfrog how to do so.
