Installation questions

If you have a forklift truck, you can easily remove the Extreme. Make sure the forks are located in the middle of the printer. If you do not have a forklift truck, check this video how to remove it.

When the machine is shipped, the wheels are not mounted on the machine for safety reasons. The wheels are located in the accessories box of the machine.

We recommend you to keep the box + pallet just in case you ever need to move the Extreme to another location. The box is especially designed for the Extreme and we do not recommend it to ship it in any other box.

The Builder Extreme has been tested in our factory for over 50 hours and the bed is already leveled. Please follow the instruction on the quick start and level the machine and NOT the bed. Only level the bed if needed after printing the surface test.

When the machine is shipped, you will receive an email from Simplify3D. In this email you find the instructions how to install the Builder Extreme 3D printer.

Please choose “other printers” and click ok. Click on this link: Download the FFF profile for your specific printer. Unzip the file and open Simplify3D. Go to File, Import FFF profile and upload the FFF profile. Now you have successfully uploaded the standard print settings Builder has created.

Make sure the machine has power and that the UPS system is turned on. The UPS is located behind the black control box and has a switch button on the housing. Press the switch on button for 3 seconds. The Builder Extreme will start up.

The surface test (test to check the bed is leveled correctly)  is on the memory of the printer. When the machine is pre-heated, you can press print and there you find the surface test and other standard g-codes made by Builder. These are often used as a test.

For the extruder it is best to print with 2 filaments at the same time, only when not printing dual objects. This prevents the extruder from clogging and stringing but it also improves the quality of the print. It even allows you to print up to 9 kg without filament changes. Start the gcode created in Simplify3D. As soon as the prints starts, go to tune, flow and set the extruder ratio to 50/50. Now it is printing with both filaments. If you do not want to change the ratio to 50/50 manually, go to Simplify3D, edit process settings, scripts, layer change script and set G93 R50. If you save this setting, each gcode will print 50/50.

Every Builder Extreme is tested for 50 hours. These tests are done to make sure the printer works correctly and that the print head is able to print mono, dual and color mixed objects. The filament stays in the print head for safety reasons.

Print quality questions

First of all, check the bed leveling of the machine. Print the surface test to see if the filaments sticks to the bed equally. If not, please level the bed only on the place where it is needed. Also make sure that the machine has been pre-heating for about 15 minutes before you start a large print. The bed needs some time to warm up equally.

This line is the start and stop line for each layer. You can change the position of this line in Simplify3D. Open Simplify3D and go to layer and then choose start point to specific location. Now you can decide where to position the start and stop layer.

This is called stringing. Make sure you are printing with 2 filaments at the same time and set both extruders at 50%. Now there will be less chance of stringing. Still experience stringing? Please find here some tips how to solve it with Simplif3D.

The scars are only visible on the top layer. If you want to achieve a smooth top layer, make sure you are not over extruding. Please check here for information about over extruding. If you are not over extruding, you might want to try the Z-hop.

When printing an object with very fragile support, make sure you first print a solid layer under the support. This makes the support much more stable. Go to Simplify3D, edit process settings, support and add a Support Base Layer of 1 or 2.

Always make sure you print 50/50 with both extruders when not printing dual colored objects. If your object feels very fragile, check if the silver handles near the filament, are levelled. It could be that one of the extruders did not feed any filaments. So it means that your product is only printed with 50% filament.

When clogging during the first layer, make sure the bed leveling is correct. If the nozzle is too close to the bed, it cannot extrude its material. Please check if the correct nozzle is on the print head. The nozzles are marked with circles to see which nozzle is what diameter. Use the pressure plug to unclog the nozzle. Only do this when the other extruder is filled with filament. See the manual how to unclog. If you tried to unclog with the pressure plug and it still keeps clogging, make sure you replace the tubes of the extruder. Make sure you go back to the standard FFF profile for Simplify3D. It could be that you accidentally saved certain settings which are not ideal for your print.

When you are not printing for a few days, and you leave the filament in the print head, the filament is under tension. Make sure when you start a new print, you cut of the filament that was under tension (from filament detection till print head).

Please check if the UPS system is switched on. The UPS system is located behind the black control box. The UPS charges when its on and the green light on the control box is on. Was the UPS on, but did it not save the print? Please contact our Helpdesk here.

Technical issues

When the touch screen is black, but the print is still printing, please let the printer finish the print job. After the print is ready, switch off the UPS system and remove the power plug to fully shut down the printer. Insert the power plug again and switch on the UPS. The printer is now starting up again.

Press the switch on button for a 3 seconds. If you do it shorter, the machine will not switch on. When you hold it longer than 3 seconds and the printer doesn’t switch on, it could be that a fuse inside the control box is blown. Please fill in the support form so we assist you how to check the fuse.

When the screen freezes, but the print is still printing, please let the printer finish the print job. After the print is ready, switch off the UPS system and remove the power plug to fully shut down the printer. Insert the power plug again and switch on the UPS. The printer is now starting up again.

The accuracy of the print is determined by many different factors. Print speed, print temperature, overall temperature and material are all factors that influence the accuracy. Please check this page about how to improve the accuracy of the printed object.
