  1. Hi, Thanks for the info. I will up the heated chamber temp as recommended. I increased the printing temp to 270 and this has massively improved adhesion. I looked through the material TDS and was going to suggest Tough PLA to the client. Thanks, Carl
  2. Hi, I have previously used Stratasys ABS material with great success on there machines but have, until recently, not attempted to use ABS on Ultimakers. I now have a project where the client has request ABS as the material and have ran some samples parts in UM ABS on our S5 Pro Bundle. The parts look fantastic however, the inter-layer adhesion is terrible. Any force in the z-direction and the part will cleave quite cleanly along a layer. Parts printed so far have been with a variety of the UM recommended profiles from Cura and have also tried to increase the printing temperature. Nothing appears to make a difference. Any suggestions? Carl
  3. Sorted, thanks. There was no slack to move the microswitch when the screws were loosened. Ended up carefully bending switch bar. Thanks, Carl
  4. cheers, I will give it a go. Carl
  5. Hi, Like most Universities, we have pooled our 3D printing resources and are producing PPE items. One of the Ulimakers that has come from a different department and it is behaving a little oddly. We are printing a shield design that needs the full bed of the Ultimaker and one one printer, it prints about 15mm forward in the Y-direction. This results in part of the design being flattened (at the extremity of the part) which is not a huge problem but occasionally we are seeing a layer shift. Amongst the printers, we are running 2 UM2+ and 3 UM2ex machines and they are all sharing the same G-Code. The rest of the printers produce identical prints that are correctly centred on the plate. I have performed a factory reset on the machine and there is no visible difference between the printers. I have attached an image of the model printing in the correct and incorrect positions. Any idea what could cause this? Yours, Carl
  6. Hi, At the end of a print, our S5 paused for a brief period and then raised the print bed to about 10mm from its maximum and began its material purge (we are connected to a material station). This caused the print head to crash into the print. Fortunately, the geometry of the allowed the head to slide off but this was shear luck. We are using Cura 4.5 and S5 has latest drivers. Carl
