Print times

Over the last few months I've been able to nail down really good settings for the HS and I'm often printing flawlessly at 150mm/s (with shells, supports etc at varying levels of underspeed) with both PLA and ABS using different nozzles (including 0.5mm for fast prints). 

My biggest problem is the discrepancy between the time Simplify3D tells me a print is going to take an how much it really takes. My latest print was an 18 hour print according to Simplify3D but actually took closer to 23 hours! That's a huge miscalculation! The time remaining on the screen of the printer while printing is even less accurate because it seems to be calculating the time based on what part of the print it is printing. When I print the infill at a fast speed, the time remaining plummets, but when I print the outside shell at a slow speed, the time remaining balloons! Is there a solution for this?

I will try to explain the reason for this and if anything is unclear in any way please let me know:

1. The time Simplify 3D actually shows is a estimation based on the number of lines the gcode has and the default printing speed which is chosen;

2. Now when the gcode is loaded to the HS the gcode goes through the firmware and the firmware adjusts the speed of the print depending on how many commands the firmware will process;

To be more precise if you have a model which has the shape of a square which is defined by 4 spatial points means 4 commands;

Now the estimation which the firmware will make, will be based on the previous layers and the speed at which they were printed; So for example you will get a estimated printing time of lets say 2 hours;

However when printing if your model has multiple shapes the printing time will change:

The firmware has a buffer of 16 commands which goes in a continuous loop as one command is executed another enters (which is also why the printer will not stop immediately when you pause the print as the buffer has to be emptied). The firmware always checks the first command with the last command and adjusts the speed of the print in order to make sure that all of the loaded 16 commands will be executed properly and at the highest rate possbile but this always changes as one command is run and a new one is received;

So actually the only way you will know for sure how much a print will take is to run the gcode and time the print yourself;

In some cases when a print is quite simple the estimated time will be closer to reality.

So in conclusion there is nothing wrong with the printer it is actually more to do with how Simplify 3D estimates the printing time and how the firmware processes the commands;

Let me know if this explains why the estimation Simplify 3D makes is not accurate.

Hi, I would like to bring this thread back to life, cause it is exactly about what I experienced to be a problem to me using a Bolt Pro. Please don't get me wrong when saying that both the print time estimation of simplify3D and the printer itself (firmware) are really an impertinence. I am using a 500,- € printer at home for private purpose and even the related and limited software of this machine is able to calculate the printing time within a range of some minutes (of course slicing process takes longer). I would much appreciate if you could improve this function as it is a really important information for professional use. If this is really the only possibility to give a rough (or whatever is the best expression) estimation of printing time I would suggest to remove it at all as it is nothing but a useless illusion.

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.

For a more thorough description of Slic3s settings please check this guide!

Windows 8
To install the Arduino drivers on a computer with Windows 8 follow these steps after downloading the Arduino software.

- Save unsaved work and write the instructions down
[your computer will reboot into startup options screen]
- Press the Windows Key and the ‘R’ key simultaneously
- Copy the command inside the brackets
–>[ shutdown.exe /r /o /f /t 00 ] – Select ‘Troubleshoot’
- Select ‘Advanced options’
- Select ‘Startup Settings’
- Select ‘Disable Driver Signature Enforcement’
- Install driver as usual via device manager


In this clip, we will explain you how you can generate a STL file using Sketchup. We show you what to download and how to export your design in STL.

Part 3 of 3: Making your first print!

In this final clip, the process of creating your first print will be explained. This starts with removing the callibration print that is already on the print bed. How to insert the filament and operate the Repetier Host Leapfrog software is also shown, which should culminate in your first 3D Print on the Creatr!

Google sketchupHow to export STL files from Sketchup

The first step is to download and install the Arduino software to make it possible for your computer to connect with the printer. You will then need to in stall this driver for OSX to recognize the hardware.

The next step is to download the Repetier 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. We have developed standard print profiles for the Creatr. Please follow the instructions below to install the print profiles for Mac [not yet included in the video]:

- Download This file
- Go to your Home Folder on Mac and select “Go to Folder” from the Go Menu en type “Library/Application Support/Slic3r/” - Unzip the file you just downloaded and dump the contents in the Slic3r folder, it will replace your existing settings. If you want to keep your current settings as well, take the contents from each folder and put this in the same folder in the Home/Libaray/App../Slic3r folder.
