cnc-multitool has produced itself – with its own machines, under real conditions, for many years. All typical mistakes were made and analysed first-hand. We share this knowledge openly – directly, honestly and practically. Because the best machine is worthless without the right production knowledge.
Wire lengths that are too long reduce cut quality, accuracy and speed. Why shorter is almost always better in hot wire cutting – and when long wires still make sense.
Learn moreHow to cut Styrofoam and EPS cleanly with a CNC hot wire – speed, temperature and wire length guidelines from real production.
Learn moreStyrodur and XPS react differently to EPS – and therefore need different settings. What really matters in hot wire cutting of XPS.
Learn moreVariable wire lengths allow short stable cuts in daily use and long wire lengths when needed – all on one machine. How it works and when it makes sense.
Learn moreWhich wire length is optimal for EPS standard blocks – and why shorter is almost always better. Practical knowledge for the right machine selection.
Learn moreWhich wire length is optimal for XPS and Styrodur – and why shorter wires are even more important with XPS than with EPS.
Learn moreHow cutting speed and wire temperature are related – and how to achieve the optimal cutting gap of approx. 2 mm in CNC hot wire cutting.
Learn moreHow wire temperature is set practically at the material in hot wire cutting – explained step by step with guidelines for EPS, XPS and EPP.
Learn moreWhy waves appear on cut surfaces in hot wire cutting – and how to prevent them through correct wire length and cutting speed.
Learn moreRough surfaces, grooves and uneven cut edges in hot wire cutting – identify causes and resolve them permanently.
Learn moreWhy the hot wire gets stuck or breaks in CNC hot wire cutting – and what to do about it. Identify causes and prevent wire breakage.
Learn moreWhen is a single-wire machine better – and when does a multi-wire machine pay off? The decision depends on production, not on the machine.
Learn moreWhat is the difference between 2-axis and 4-axis cuts in hot wire cutting – and when do I really need 4 axes?
Learn moreA rotation table is needed far less often in practice than customers assume. When it makes sense – and when to leave it out.
Learn moreMulti-wire machines significantly increase production output – but only when the production is really suited for it. When multi-wire makes sense.
Learn moreSystematic decision guide for the right CNC hot wire machine – from production analysis to machine recommendation.
Learn moreBigger is not better in CNC hot wire cutting. Why oversized machines deliver worse quality and cost more.
Learn moreNeopor is EPS with graphite content – and presents special challenges in hot wire cutting. What to consider and which machines are suitable.
Learn moreThose who plan production first and then buy the machine make better decisions. Why production planning matters more than machine selection.
Learn moreHot wire and router complement each other perfectly – hot wire for rough contours, router for details. When and how to combine both.
Learn moreIn monolithic cutting there are no visible entry marks. How it works and when it makes sense.
Learn moreHow large EPS blocks are moved safely and efficiently to the hot wire machine – loading concepts and practical tips.
